I have the same problem here on a medium loaded newsserver (6 GB newsspool). I get "panic: vm_fault: fault on nofault entry, addr: f6718000" with different values for addr. I updated from 2.1.5 to 2.2.1 about 48 hours before I've seen this problem the first time. I really have no idea what to do now. The machine always reboots some minutes after the crash. Running fsck on 10 GB disks all the time is no fun... :/ If you have any idea how I can make the uptime 6 hrs or higher, please tell me!
