(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.
