Re: [Xenomai-help] NMI watchdog: Loading of xeno_native leads...

["M. Koehrer" <mathias_koehrer@domain.hid>]

Hi!

It was the compiler!!! Using gcc-3.3 solved the issue.
That means, that somehow gcc-4.1.2 must not be used with Xenomai currently...
 
This allowed me to catch the system hang I was hunting for since yesterday...
And I got it.
I write the information I found on the console (I have not tried with console redirection yet...).
CPU 0, eip c010122d
EIP 0060:[<c010122d>]
EFLAGS 00000246
EIP is at mwait_idle_with_hints+0x2c/0x2e
eax:0 ebx:c0498000 ecx:0 edx:0

Call Trace
mwait_idle+0x0/0x2e
mwait_idle+0x1d/0x2e
cpu_idle+0x44/0x86
start_kernel+0x1f1/0x1f5
unknown_bootoption+0x0/0x191

I'll try to reproduce the same with console redirection, however, I hope this could help already!

Regards

Mathias
