running ploplinux on i586

[toddjerret]

hello,

I am trying to run plop from the network on two thin-clients.
it works on one and the other gets a kernel-panic soon after starting.

the main diferent is that one has i686 processor and one has i586 processor.
is it posible that plop dous not support i586?

with regards

Todd

[Elmar]

hi,
ploplinux is compiled to run on i486, so it should work on an i586. can you post a photo of your monitor with the kernel panic?

[toddjerret]

hi,
thanks for the quick replay,

I am trying to get it running on a ebox-3300mx like in www.wdlsystems.com

the screen cannot be captured, I can copy it to paper and then write it down.

the panic line is: Kernel Panic - not syncing: attempted to kill init!

Todd

[Elmar]

i mean, simply make a photo with a camera and post it.

or write down the 4 lines before the kernel panic

[toddjerret]

ok, the few lines before the panic are:

wbsd: winbond w83151xd sd/mmc card interface driver
wbsd: copyright (c) pieere ossman
usbcore: registrated new interfacedriver usbhid
usbhid: v.2.6:usb hid core driver
tcp cubic registrated
net: registrated udp transport module
net: registrated tcp transport module
freeing unused kernel memory: 472k freed


hope you can make something out of this

replace this test initramfs.gz with yours (in syslinux/kernel/).
http://download.plop.at/tmp/initramfs.gz

is there still a kernel panic?

[toddjerret]

hi,

just wanted to be sure : the file you posted replaces initrfs.gz witch is in the same directory as my bzimage file - correct ??

if so the behavior is the same = kernel panic

Todd

[Elmar]

it seems you are not using the latest ploplinux version. when you use an older version then you have to replace it with initrfs.gz (as you did).

here is a second test file http://download.plop.at/tmp/initramfs2.gz

[toddjerret]

you are correct, I am using the 3.8.4 version.

the second version gives the same result .

Todd

[Elmar]

its possible that its a problem with the squashfs 3.x decompression. is there any reason for using the old ploplinux version? you should try a new version

[toddjerret]

the reason is that i have a running environment with 3.8.4 version.
I will try to download the newest version and let you know how it went.

[toddjerret]

I downloaded the 4.1 version and copyed it to the right directory's.

when booting I get the folowing:

decompressing Linux ... Parsing ELF ... done.
Booting the Kernel.


and the kursor is blinking and blinking

Todd

[Elmar]

no other output? did you add the "quiet" parameter? if yes, then remove it

[toddjerret]

no, this is the strange thing...
nothing else on the screen.

on another thinclient of another brand it go's all the way to level3 prompt.

[Elmar]

you try to start without framebuffer mode?

[toddjerret]

sorry for asking but - how do i do that ??

[Elmar]

when you use no vga parameter or vga=1 then you start without framebuffer
btw. how much ram do you have in the pc?

[toddjerret]

I have vga=1 in all my images allready.
it has 500MB ram and no disk as the machine is booting from the network .
any ideas?

[Elmar]

add pnpbios=off after vga=1

it seems the ebox-3300 has some problems with 2.6 kernels

[toddjerret]

same response on 3.8.4 and 4.1.0 with pnpbios=off

still the same.

[Elmar]

try this kernel http://download.plop.at/tmp/bzImage

[toddjerret]

Hi Elmar,

took a few days of ...

tryed the temp kernel you sent and no luck.
the dump on the screen looks diferent :

cpuid: using governor ladder
cpuid: using governor menu
using IPI No-shortcut mode
Magic Number: 4:974:810
Freeing unused Kernel memory
Write protecting the kernel text: 2164k
Write protecting the kernel read-only data 836k
init used greatest stack depth 6804 bytes left
Kernel panic - not syncing: Attempted to kill init!

hope again this meens somthing to you

regards

Todd

[Elmar]

thats a step forward, i give you a new test kernel

[Elmar]

here are the new test kernels
http://download.plop.at/tmp/bzImage2
http://download.plop.at/tmp/bzImage3

[toddjerret]

well after trying the two new kernel the output is the same except for
after the Call Trace dump a new line is there that says:

ohci-hcd 000:00:ob.0: auto-stop root hub

[Elmar]

do you see those lines at the end? (the values are not important)

Write protecting the kernel text: 2164k
Write protecting the kernel read-only data 836k
init used greatest stack depth 6804 bytes left
Kernel panic - not syncing: Attempted to kill init!

[toddjerret]

yes, the lines are the same.

[Elmar]

new test http://download.plop.at/tmp/bzImage4

[toddjerret]

with the bzimage4 the result is back to :

decompressing Linux ... Parsing ELF ... done.
Booting the Kernel.

and nothing else

[Elmar]

new test http://download.plop.at/tmp/bzImage5

[toddjerret]

with the bzimage5 its the same :

decompressing Linux ... Parsing ELF ... done.
Booting the Kernel.

and nothing else

[Elmar]

strange

[Elmar]

i think i now whats wrong
new test http://download.plop.at/tmp/bzImage7

[toddjerret]

with bzimage7 - same result.

Todd

[Elmar]

i think you see "init used greatest..."
new test http://download.plop.at/tmp/bzImage8

[toddjerret]

same result with the big filesize bzimage8,

and fyi - "init used greatest..." is not there from the bzimage2 and up to bzimage8.

[Elmar]

and fyi - "init used greatest..." is not there from the bzimage2 and up to bzimage8.

but you posted it with bzimage6

[toddjerret]

sorry, my bad.
you are correct, in bzimage6 it was there and in bzimage7 and bzimage8 it was not.

[Elmar]

new test http://download.plop.at/tmp/bzImage9
its important that it goes to "init used greatest..."

[toddjerret]

nothing changed.

same results with no  "init used greatest..." (I checked and double checked)

Todd

[Elmar]

http://download.plop.at/tmp/bzImage10
http://download.plop.at/tmp/bzImage11

[toddjerret]

same result with bzimage10,11 with ither plop3.8.4 and plop4.1.0.

[Elmar]

no "init used greatest..." on the screen?

[toddjerret]

no, I am positive cos I know it is importent.

[Elmar]

http://download.plop.at/tmp/bzImage12

[toddjerret]

as you emphasise the "init used greatest..."  line,
I tryed to load the bzimage6 again and I can not see this line again.
no metter what i do (diferent versions and diferent initram files, tryed downloading the image again from the link...)

I can not explain it and I tripled checked it.
I don't know what has changed .

p.s. with the latest bzimage12 the results are the same.

[Elmar]

http://download.plop.at/tmp/bzImage13

you have to test only with 4.1.0. currently only the kernel is loaded, so either it woks or it doesn't.

"results are the same" can mean a lot, so
when it hangs right after the message "booting the kernel." simply write "bad".
when it goes up to "init used greatest" then write "ok".
when it hangs between those 2 states, then tell me what you see.

[toddjerret]

well..  OK. for bz13

[Elmar]

http://download.plop.at/tmp/bzImage14

[toddjerret]

bz14 - kernel panic- with NO "init used greatest..." .

[Elmar]

what are the last 3 lines?

[toddjerret]

Write protecting the kernel text: 2164k
Write protecting the kernel read-only data 836k
Kernel panic - not syncing: Attempted to kill init!

[Elmar]

ok, this is perfect.
can you try to boot with the bzImage14 and the original initramfs.gz from 4.1.0

[toddjerret]

tryed it with the same results.

[Elmar]

and with this http://download.plop.at/tmp/initramfs.gz

[toddjerret]

same as before only one line added before the magoc number line:
hash maches drivers/base/power/main.c: 525

[toddjerret]

I have to leave for today,
I appreciate your help alot.

Tod

[Elmar]

this package should work fine http://download.plop.at/tmp/ploplinux-4.1.1-test.tgz

[toddjerret]

Hi,
this looks alot better.
it start to roll the start lines and then it stops at:

INIT: Entering runlevel:3
INIT: cannot execute "/etc/rc.d/init.d/rc

p.s. I connect it to the 4.1.0 sqfs files and pluspack from the 3.8.4 with all my scripts and files.

[Elmar]

you have to use all sqfs files from the test package.

you have to copy your own scripts to ploplinux/bin/ but this only needed when the ploplinux booting works

[toddjerret]

works fine

know I have to migrate all my workspase to the new environment.
the opt has an old sqfs version so it will not load and I will have to figure out the changes from the old version.
I will try to do it and will let you know how it went.

thank you very mouch for your help and dedication thru the last few days.

Todd

[Elmar]

fine. btw. the problem was
kernel: not rerouting broken irq's
init: glibc, i recompiled it with the correct setting --build=i486-pc-linux-gnu

you can use the opt.sqfs from 4.1.0 http://www.plop.at/en/ploplinuxdl.html
save it in ploplinux/opt/

best regards
elmar

[toddjerret]

Hi,

allmost averything is working fine.
I am having problem with "No soundcard found" in all of the devices I tryed it on (some work fine with the 3.8.4 version)

Todd

[Elmar]

add the command "pciprobe" to ploplinux/bin/rc.local
