[Xenomai-help] Kernel Panic at boot 2.6.15

[Xenomai-help] Kernel Panic at boot 2.6.15

[Brian L.]

I just patched 2.6.15 using the prepare-kernel script and adeos patch
included in xenomai 2.1.0. I configured the kernel in a sensible way
for the hardware, but didn't touch anything in the real-time section.

When I boot the kernel, I get a kernel panic. Here's some important
bits (everything above this is cut off and obviously, unscrollable):

Pricess swapper (pid: 1, threadinfo=c12900000, task=c1283a30)
Stack: ...

------

The hardware is a UP 440bx with a celeron 566 coppermine.
CPU/memory/mainboard have been ruled out as failure points. Kernel is
configured as celeron/coppermine and xenomai as i686.

I trudged through the archives a bit and it seems that this problem is
somewhat tragically unique. Any xenomai-kernel-internals hackers want
to give this a go? Is there anywhere I should look first? I'm an
rtlinux refugee, so my knowledge of adeos/rtai internals is limited.

Thanks,
Brian

...unfortunately not all of the important bits (i.e. the actual oops
which includes information about what function failed and also register
content).

Anyway, this function is the one calling the crashing code, and there
are only APIC related functions in it. You may want to try switching off
local APIC in the kernel config. Does APIC work for standard Linux on
your board?

Err, no RTAI here, you are on Xenomai-core. ;)

This is the second time this random bug is reported, so there must be 
something fishy here. Please rebuild your kernel with 
CONFIG_FRAME_POINTER enabled, so we have a readable backtrace.

This really looks like :
https://mail.gna.org/public/xenomai-help/2006-03/msg00112.html

Which was fixed by revision 786 in trunk and 787 in v2.1.x branch.

The real issue is that you enabled support for APIC in kernel
configuration, and your CPU either has no APIC, or it is disabled by
Linux because disabled by BIOS.

Try adding "lapic" as a kernel parameter, and if it still does not work,
disable support for APIC in the kernel configuration and rebuild your
kernel.

Indeed, comparing to the traces I have received on the other issue, this 
must be the same problem.

[emin ak]

I had this problem before, disabling power management (APIC ) on
kernel configuration solved the problem (but I dont know why?),Maybe a
previous topic named 'Crashing at boot with 2.6.15.4' was related with
this problem that fixed in the newest version, you can have a look at
it.
