I woke up this morning and discovered that a compile had died due to I/O
errors. I found the following in my logs (the rest of the relevant bits
from the log is attached -- 5k bz2, 146k uncompressed). Preempt is on,
htree is in use, e2fsck worked fine.

hmm. it really looks like memory problem. have you tried
to test it? all the corruptions happened at the same address.
