2.5.3-pre4 panics on boot )-:

[Anton Altaparmakov]

oops is below...

Can't attach .config nor decode oops at the moment as the machine is now 
dead (I am remote), I can reboot it remotely but LILO doesn't accept my 
remote commands (even though I send a break signal it doesn't do anything, 
just sits at prompt and after time out boots into -pre4 and dies - any 
ideas?). )-:

Is there a patch I can apply to fix this panic? Assuming one of the 
scheduler ones. But which one?

Best regards,

Anton

In arch/i386/kernel/smpboot.c find
	global_irq_holder = 0;
and s/0/NO_PROC_ID/

Normally that would suck but this is a BUG, so no problem...

Scheduling in an interrupt?  Ouch.

I would assume Ingo's latest, which is J6 AFAICS:
http://people.redhat.com/mingo/O(1)-scheduler/sched-O1-2.5.3-pre4-J6.patch
