[Xenomai-help] TR: Kernel panic with (Kernel-2.6.27/Xenomai -2.4.6)

[-- Attachment #1.1.1: Type: text/plain, Size: 823 bytes --]

Hello,
 
I have compiled and installed linux kernel 2.6.27 in a fedora distro running
in Virtualbox. Everything worked fine.
After that, I patched the kernel using xenomai-2.4.6 script
"prepare-kernel.sh". So, the adeos patch used was
adeos-ipie-2.6.27-x86-2.1-01.patch. No problem.
 
Then I have configured the newly patched kernel for activate xenomai and
nucleus (find the .config file in attachment). I compiled the kernel. No
error, no problem.
 
But when I boot the patched kernel, it produces a panic, apparently in
xeno_sys_init (look at the screen copy of vitualbox).
 
Any clue ?

Do you have the same error if you boot this kernel on a real machine ?

Sorry for the delay.

It seems it was a problem specific to VirtualBox. The same kernel works fine
on a real machine.

Thanks for your help

It /might/ be a problem of this VM, but often the different timing of
these environments triggers races that only rarely occur on real hw. For
x86, I'm doing a lot of debugging and stress testing (not latency
testing, of course) under KVM. And I found no problem that was due to
the VM - at least on that platform which is, granted, much more
hardware-like than VirtualBox as it only uses HVM.

So, when time permits, it would be good to try catching the full trace
(redirect kernel console to serial port, record output on that virtual
serial port) and disassemble (objdump -dS vmlinux) the function that is
reported to fail.

Thanks,
Jan

Try Xenomai-2.4.6.1. This problem was fixed there.
