This has been observed on FreeBSD 6.3-RELEASE i386 with following error: Fatal trap 12: page fault while in kernel mode fault virtual address =3D 0xf4d988d8 fault code =3D supervisor read, page not present instruction pointer =3D 0x20:0xc0847e06 stack pointer =3D 0x28:0xc0c20bfc frame pointer =3D 0x28:0xc0c20c40 code segment =3D base 0x0, limit 0xfffff, type 0x1b =3D DPL 0, pres 1, def32 1, gran 1 processor eflags =3D interrupt enabled, resume, IOPL =3D 0 current process =3D 0 (swapper) trap number =3D 12 panic: page fault I wasn't able to get the machine up into any mode except to the basic = prompt. This problem can also be duplicated if you move the drive from ICH9R = RAID to non-RAID controller Any tips on how to get the FBSD system operational again without having = to do a reinstall?
