I've booted 2.5.46bk5 on the machine, and it has been running for over
2 hours with extra heavy diskio. That reliably crashed the machine
in about 45 minutes with 2.4.45 and 2.5.46, machine is still up now.

Indeed, I don't see that one anymore in -bk5
I'm still seeing the buffer layer error at fs/buffer.c:1623,
though. Happens when a blockdev is close()d. Is a fix for
this in -mm2? Does -mm2 include -bk5 ? If so I'll put that
on it and keep an eye on it tomorrow, see what happens.
Debug messages I'm still seeing:
(note that I compiled IPv6 into the kernel since we're slowly moving
our network to IPv6 but that it is otherwise unused right now, and
that the previous kernels that crashed on me didn't have IPv6 in it)
Uninitialised timer!
