I just joined this thread today, but had a similar issue with an IBM 305
machine.
On 4.5, it would randomly just shut down. No reason. Nothing in any
logs, it was as if the power was pulled.
I have 2 identical IBM 305 machines and it was happening on both, so
that technically ruled out any specific hardware failure.
What I did notice (in the BIOS events) was that the IBM reported fan
#1,2,3 loss. Something seemed to disrupt the fan speed to bios reporting
and I suspect the machine powered down since it thought it was
overheating? - I could go a day or 2 weeks. Very random.
4.6 hasn't done this (yet) and uptime has been over a month.
However, eventhough both IBMs are the same in every way, 4.6-REL will
boot on machine #2 but I have no networking. If I use a 4.6-CUR
snapshot, it comes up fine. That makes NO sense, yet another user
reported the same exact thing.
