I've been trying 2.5.x on and off on our newsserver. It's a dual
PIII/450, 1 GB RAM, acenic GigE adapter, and it does lots
of I/O: 40 mbit/sec sustained in, 110 mbit/sec sustained out,
all from/to disk and history database.
Under 2.4.x the box is dead stable.
But in 2.5, after a few hours the box usually spontaneously
reboots. Last night it didn't reboot, it just hung after a:

I tried again today and it crashed, produced a nice (slightly
garbled, alas) crash message and rebooted.
Log is below. c1a15abe etc addresses are outside of anything in
System.map, and the only module I have loaded is the acenic
module. Could that be the problem ?
