We had a dual Xeon Sun box (with an Intel Mobo) running 2.6.5, LVM2 and
software RAID, as an NFS server. Gave us no end of trouble under load
(kept kernel panicing). Soon rebuilt it without LVM and with a 2.4.26
kernel. Much more stable! These days it is running a 2.6.8 kernel and
software RAID with some issues, but nowhere near as bad as when we were
using LVM.

Just my A$0.02 worth.
