Hi, We have a machine with ASUS A67V8-X mobo and AMD 2600+ CPU. FreeBSD 4-STABLE from like four weeks ago. It crashing three times per day, most often when CPU is working hard, typically during compilation. Example excerpts from messages: May 13 17:28:08 fikon /kernel: panic: pmap_release: non ptd page May 13 17:28:08 fikon /kernel: May 13 17:28:08 fikon /kernel: syncing disks... 57 16 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 and May 12 16:42:34 fikon /kernel: May 12 16:42:34 fikon /kernel: May 12 16:42:34 fikon /kernel: Fatal trap 12: page fault while in kernel mode May 12 16:42:34 fikon /kernel: fault virtual address = 0xbfd40d7c May 12 16:42:34 fikon /kernel: fault code = supervisor read, page not present May 12 16:42:34 fikon /kernel: instruction pointer = 0x8:0xc031100f May 12 16:42:34 fikon /kernel: stack pointer = 0x10:0xe91ffed0 May 12 16:42:34 fikon /kernel: frame pointer = 0x10:0xe91ffee0 May 12 16:42:34 fikon /kernel: code segment = base 0x0, limit 0xfffff, type 0x1b May 12 16:42:34 fikon /kernel: = DPL 0, pres 1, def32 1, gran 1 May 12 16:42:34 fikon /kernel: processor eflags = interrupt enabled, resume, IOPL = 0 May 12 16:42:34 fikon /kernel: current process = 16902 (postgres) May 12 16:42:34 fikon /kernel: interrupt mask = net bio cam May 12 16:42:34 fikon /kernel: trap number = 12 May 12 16:42:34 fikon /kernel: panic: page fault May 12 16:42:34 fikon /kernel: May 12 16:42:34 fikon /kernel: syncing disks... 20 5 4 4 4 4 4 4 4 8 2 2 2 2 2 2 2 5 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 To me, this looks like hardware problems. Do you agree or disagree? Can there be anything else? Memory, mobo or CPU? Regards, Palle
