Mounting an audio cd on acd0c and acd1c (cd-r and cd-rw) without specifying the filesystem type caused a system panic.

The system panic output follows: -------------------------------- panic: vmfault : fault on nofault entry, addr: c3dab000 Fatal trap 12: page fault while in kernel mode fault virtual address = 0x30 fault code = supervisor read, page not present instruction pointer = 0x8:0xc01cfefc stack pointer = 0x10:0xc026e6b0 frame pointer = 0x10:0xc026e6b4 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 = idle interrupt mask = bio trap number = 12 panic: page fault ------------------------------- Regards from Germany, Thomas Seck To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
