Hi, I reported this before, but I am very surprised that it is still the case: (This is from the last time it happened; this time the box rebooted and cleared the serial console before I had time to cut/paste it. > Fatal trap 12: page fault while in kernel mode > cpuid = 1; apic id = 00 > fault virtual address = 0x1c > fault code = supervisor write, page not present > instruction pointer = 0x8:0xc0620b5f > stack pointer = 0x10:0xdadbd988 > frame pointer = 0x10:0xdadbd994 > code segment = base 0x0, limit 0xfffff, type 0x1b > = DPL 0, pres 1, def32 1, gran 1 > processor eflags = interrupt enabled, resume, IOPL = 0 > current process = 51999 (getty) > trap number = 12 > panic: page fault > cpuid = 1 > boot() called on cpu#0 > Uptime: 66d11h24m50s The above panic will show up occasionally when logging out from a serial console (i.e. ctrl-D, logout, exit, whatever). This is EXTREMELY BAD, as it will crash an otherwise perfectly healthy box at random - and renders the serial console useless. Robert Watson confirmed this to be an issue on the 10th of April. Anyone?? /Eirik
