Hello!
I've installed the 3.0-CAM-19989712 on my Tyan Titan Pro (2x200 MHz
PPro, 64 MB RAM). The machine works fine, but instable!
I stressed the machine a whole day by a loop of
make -j 4 clean buildworld
without any problems. A parallel 'dump 0' onto DAT, no problem.
But then a simple 'emacs /etc/crontab' or a simple desktop change,
or .... any other simple action, without any load on the machine
leads to a instantaneously freeze of the system (mouse locked, no
panic, no reboot, no kdb, ..., only a hard reset helps). One time
it dies during a simple kernel compile cycle. It's not deterministic
reproducible!
After changing the RAM (replace the installed 64MB by another set,
adding further 64 MB, so all 8 slots are occupied), drop speed of
the BIOS RAM access time. I didn't believe in a hardware error,
perhaps one of the PPro caches are buggy, but in single Processor
mode I have never such problems (tested with both processors!).
What can I do to further debug this problem, what information do you
need?
Any other person out there, who has similar problems?
Thanks
Lars
