FreeBSD 3.1-RELEASE as retrieved on 3/18. dual 400 mhz pentium
ii's, 512 megs ram, adaptec 2940 controller, 9 gig scsi barracuda
drive(seagate). known good machine, was running 2.2.8-stable.
>Description:
did clean install of 3.1-release. rebooted, rebuilt kernel
(maxusers=512, nmbclusters=16384, removed unused device entries). rebooted,
kernel crashed after mounting partitions.
rebooted, built debugging kernel and did strip -g on a copy. installed copy.
set up dumpdev to point to swap, and had savecore run on crash.
NOTE: setting MAXMEM=32768 caused kernel to boot with no problems. however,
this machine had been in use for several months running 2.2.8-stable. also,
have experienced this with 4 other known good machines.
Here are the results of the stack trace on the kernel:
