Hi! I had a kernel panic today with a amd64/7.99.3 kernel from Dec 20. The last activity I had started was downloading a file from network to an NFS directory mounted from a Synology.
I don't know if that's related, but there was no particular load on the machine. >From dmesg after reboot: uvm_fault(0xffffffff811cf2c0, 0xffff8003393b8000, 1) -> e fatal page fault in supervisor mode trap type 6 code 0 rip ffffffff8028b965 cs 8 rflags 10202 cr2 ffff8003393b8000 ilevel 4 rsp fffffe813bcb8728 curlwp 0xfffffe8825ee1220 pid 0.143 lowest kstack 0xfffffe813bcb52c0 panic: trap cpu8: Begin traceback... vpanic() at netbsd:vpanic+0x13c snprintf() at netbsd:snprintf startlwp() at netbsd:startlwp cpu8: End traceback...

(gdb) Is this a valid backtrace? Does it give any useful hints? Thomas
