Re: 2.6.19-rc6 : Spontaneous reboots, stack overflows - seems to implicate xfs, scsi, networking, SMP

Ok, that seem like another approach. What about putting your allocation slowpath 
in a kernel thread. They might have more stack available.

This is inferior to the complexity reduction suggested from the kernel people,
but if you cannot reduce complexity anymore this might work, too.
