Hi, I was able to duplicate this problem - it only occurs when the bay driver is built-in, not when the bay driver is compiled as a module. While I work on the fix for the problem, you can as a temporary workaround just use ACPI_BAY=m. By the way, I also found that the bay driver will not build at all if ACPI_DOCK=n. Oops. I will fix that too. thanks, Kristen > > When compiled with ACPI_BAY=n, it boots fine. > > The traces are hand-rewritten (no serial console on that machine), so I > have omitted the code offsets in the stacktraces. > > ACPI: ACPI Dock Station Driver > ACPI: \_SB_PCI0.IDE0.SCND.MSTR: found ejectable bay > ACPI: \_SB_PCI0.IDE0.SCND.MSTR: Adding notify handler > PM: Adding info for platform:bay.0 > ACPI: Bay [\_SB_.PCI0.IDE0.SCND.MSTR] Added > BUG: at lib/kref.c:32 kref_get() > kref_get+0x34/0x3b > kobject_get+0xf/0x13 > get_bus+0xe/0x1d > bus_add_driver+0x13/0x165 > init_waitqueue_head+0x12/0x1e > bay_init+0x57/0x79 > find_bay+0x0/0x2c4 > init+0x88/0x16d > restore_nocheck+0x12/0x15 > init+0x0/0x16d > init+0x0/0x16d > kernel_thread_helper+0x7/0x10 > ========== > BUG: at lib/kref.c:32 kref_get() > kref_get+0x34/0x3b > kobject_get+0xf/0x13 > kobject_init+0x5d/0x70 > kobject_set_name+0x5c/0x92 > bus_add_driver+0x50/0x79 > bay_init+0x57/0x79 > find_bay+0x0/0x2c4 > init+0x88/0x16d > init+0x88/0x16d > kernel_thread_helper+0x7/0x10 > ========= > > -- > Jiri Kosina > - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
