You could if you have time try this and enable CONFIG_I386_IRQSTACKS
but don't enable CONFIG_I386_4KSTACKS and see if that helps...

That sounds very interesting, I'll give it a try monday.


There are also stack debugging config options; one that will warn if you are about to overflow (CONFIG_DEBUG_STACKOVERFLOW) and one that will print max stack depth in sysrq-t output (CONFIG_DEBUG_STACK_USAGE).
