Panic does not occur with ida(4) driver disabled. Last message before panic on verbose boot is: GEOM: new disk idad0 DDB trace at panic shows: ida_construct_qcb() ida_submit_buf() idad_strategy() g_disk_start() g_io_schedule_down() g_down_procbody() fork_exit() fork_trampoline() Panic is: Fatal trap 12: page fault while in kernel mode supervisor read, page not present pid is 4 (g_down) The panic occurs on ida_construct_qcb+0xca: movzbl 0x5c(%eax),%eax which looks very much like the spot where this function bzero()s the hardware qcb. This was previously reported on the current mailing list by Ventsislav Velkov <veno@evrocom.net> on 31 March 2003 (Message-Id: <006401c2f776$d16f0230$23f00ad9@beatle>) on similar Compaq hardware. It is likely that this bug has existed at least since that time. (This is a correction to pending/53238 which was mangled by my mail client, sorry.) >How-To-Repeat: Attempt to boot 5.1-RELEASE or 5.1-CURRENT SNAP's (either floppy or CD) on systems with ida(4) supported hardware with at least one volume configured on the ida controller. >Fix: Unknown. >Release-Note: >Audit-Trail: >Unformatted:
