I'd be surprised if an ext3 bug could cause a freeze as solid
as this one. ext3's write submission patterns are somewhat different
from other filesystems, and we've exposed a few problem in underlying
layers in the past because of this. But who knows...

Have you enabled the NMI watchdog? nmi_watchdog=1 on the LILO

Also, I'd be inclined to enable all the kernel debug options,
including SLAB debug.
