Subject2.0.22/SMP: Aiee killing interrupt handler
Date
From
Got this under and SMP box while running a torture test: a huge (2G
virtual mem) job beating on the machine, with another machine hitting
it with a 'ping -f -s 4' on an isolated 10B/T network. After a two
days of running, we got the message. Note the box is still running,
and doesn't seem to be causing any trouble (we did have to resuscitate
the interface by manually bringing it up and down).

Our hardware is a Supermicro P6DOF (Orion chipset) dual PPro/200/512k
motherboard, 512M RAM, Buslogic 958 SCSI controller, 3 SCSI drives (1
Quantum, 2 IBM, 4G each), Matrox Millenium graphics card and an SMC
Etherpower 10/100 ethernet card (which is on IRQ 15). We are using the
digital de4x5.o driver (as a module) for the ethernet card. Kernel
2.0.22.

I couldn't find the EIP in System.map, I'll happily send it along if
anyone would like to take a look. Note that StructDynamics was not the
gigantic process, it was just an additional process we had running to
help hammer the machine.

Ksymoops says:

Using `/System.map' to map addresses to symbols.


Code: movb $0x1,0x1a(%edi)
Code: xorl %ebp,%ebp
Code: movl 0x538(%esi),%ecx
Code: movl $0x28,%eax
Code: shll %cl,%eax
Code: movl %eax,(%eax)
Code: nop
Code: nop
Code: nop

And here's the snippet from messages:
