I posted this message on freebsd-smp also...sorry for the bandwidth suck but
since I didn't get a reply there I thought I'd try here...
---------
I'm experiencing trouble with an older (yet new to me) ALR 2-way P133
machine. It seems to run fine with only one processor, but when I try to
bring it up with a SMP kernel I get periodic crashes that seem to be
attributed to processor 1 (more detail below). It seems to be only MP1.1
compliant, I can't find any settings in the BIOS for MP1.4. BTW: I'm using
FreeBSD 3.3-RELEASE.
The SMP kernel tends to stay up for 6-15 hours between crashes, and I've not
been able to come up with any repeatable conditions to cause it. I run this
machine predominantly as a web server (less than 5000 hits/day), with a
number of associated scripts (all in perl). On crashing, I get messages on
the screen, but not in the log files...
I've tried a number of builds and options. When compiled with the
NO_F00F_HACK flag in a SMP kernel, the system will generally reboot itself
after crashing, but otherwise it behaves no better. Unfortunately I'm out
of ideas to try and beyond my limited knowledge, so I'm hoping someone can
help me.
One other strange thing is the output from mptable. I do not get any output
regarding "MP Config Base Table Entries". Is that normal for a system like
this?
Anyone able to help me on this? Am I simply going to have to let that
second processor sit limp and lifeless? Any info or help greatly
appreciated!
Some details on crashes:
below is some of the output on the screen from one crash that seems relevant
(this is from a kernel without the NO_F00F_HACK option):
