Over the last couple of days, with no changes in configuration, one of my boxes has started to die with increasing frequency, throwing up errors like this: Fatal trap 12: Page trap while in kernel mode Fault virtual address = 0x2c2 fault code = supervisor writ, page not present instruction pointer = 0x8:0xc0272faf stack pointer = 0x10:0xd54e8cf4 frame pointer = 0x10:0xd54e8d0c code segment = bas 0x0, limit 0xffffff, type 0x1b = DPL0, pres1, def 32 1, gran1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 15 (random) trap number = 12 panic: page fault syncing disks, buffers remaining... panic: free locked buf Terminate ACPI Although it announces that it is about to reboot, it just goes to a blank console in which even the reset button has no effect (actually it does cause the HDD LED to flicker for a few seconds). Increasingly, cycling the power goes to the same foreboding blank monitor without even a murmur from the BIOS, let alone an attempt to boot FreeBSD. All the hardware is around two months old - an MSI KM2M motherboard with AMD Athlon 2200, 512MB RAM and 2 x 60 GB HDD in software RAID 1 using Vinum. FreeBSD is 5.1 RELEASE. -- Chris Hastie
