The primary reason it's not 4KSTACKS already is that I run multiple XFS partitions on top of an md RAID 1. LVM isn't involved, however, and I'm not using any other filesystem overlays like dm. I'm fairly sceptical that it's a stack overflow, but I'll be sure to enable the debugging option on the next try. > that hw monitoring thingie... I'd turn it off.

Well, GCC 3.4 kernels seem to run fine with it, but as I said to Linus I'll be sure to turn this and the sound drivers off in the next build. -- Cheers, Alistair.
