Hi.
In the last three weeks, I've been encountering trap 12 panics
caused apparently by different programs, which is odd because
this system has been running -current without a hiccup for
at least a year.
This occurs with a system built after Marcel's sigset_t changes,
and manages to make world in single user mode, which makes
me question hardware failure.
I've included the output from gdb -k kernel.6 vmcore.6
and the dmesg output. If anything else needs to be done to diagnose
this kind of crash, please let me know. I've had it crash
due to gunzip and cron as well. In most cases, the machine
is not in use, and it occurs at night.
I rebuilt X as well. AMD and NFS are running, but are not used.
The system is a Pentium I 200 with 114MB RAM, 3 IDE drives (using
Soren's ATA code), an Adaptec 1542 which has two CD-ROM drives
attached and softupdates enabled on two partitions. There is a
Vibra 16 sound card, but this hasn't worked since newpcm.
TIA.
