(This is a follow up to earlier messages I sent to freebsd-smp because
then I thought it was an smp issue - now I am not so sure.)
I have been experiencing some panics on my dual processor Xeon system.
It can take up to a few days for a panic to happen, and it seems to
happen under heavy loads.
I have set the dumpdev variable in rc.conf as the instructions say, and
indeed a "reboot -d" does actually generate a good dump. But for some
reason this particular panic refuses to create any dump at all.
The instruction pointer is at 0xc060b885, and:
nm -n /boot/kernel/kernel | grep c060b
c060b09c t pgadjustjobc
c060b128 T fixjobc
c060b240 t orphanpg
c060b390 T fill_kinfo_proc
c060b3a4 T fill_kinfo_thread
c060bbbc T pstats_alloc
c060bbd8 T pstats_fork
c060bc08 T pstats_free
c060bc1c T zpfind
c060bc98 t sysctl_out_proc
c060bf20 t sysctl_kern_proc
I am using a recent version of RELENG_5 (last make world was about March 4).
The disk is a RAID 0 twe0: <3ware Storage Controller. Driver version
1.50.01.002>
I am not suspecting hardware problems, because of the consistency of the
value of the instruction pointer when the crash occurs.
I am now going to try the system with HTT disabled. Maybe it will crash
likewise if I wait long enough.
Here is my config file
