I don't see any cmd40x_init(), I guess it's about cmd640 chipset, then cmd640x_init() I don't see very recent changes in drivers/ide/cmd640.c But there are some in drivers/ide/ide-io.c and drivers/ide/ide-cd.c for this cycle. Especially commit a1f9a89c90b4ac143c5b6054c2a157572b272cd2 which fixed in -rc2: Kernel Fault: Code=26 regs=8ed34c40 (Addr=00000024) IASQ: 00000000 00000000 IAOQ: 1034b5ac 1034b5b0 IIR: 4ab30048 ISR: 00000000 IOR: 00000024 CPU: 0 CR30: 8ed34000 CR31: ffff55ff ORIG_R28: 00000000 IAOQ[0]: ide_complete_rq+0x2c/0x70 IAOQ[1]: ide_complete_rq+0x30/0x70 RP(r2): cdrom_newpc_intr+0x178/0x46c Backtrace: [<1035c608>] cdrom_newpc_intr+0x178/0x46c [<1034c494>] ide_intr+0x1b0/0x214 [<1016d284>] handle_IRQ_event+0x70/0x150 [<1016d4b0>] __do_IRQ+0x14c/0x1cc [<102f7864>] superio_interrupt+0x88/0xbc [<1016d284>] handle_IRQ_event+0x70/0x150 [<1016d4b0>] __do_IRQ+0x14c/0x1cc [<10112efc>] do_cpu_irq_mask+0x9c/0xd0 [<10116068>] intr_return+0x0/0x4 Looks very similar. But the crash reported in this ticket is for -rc4, which means the issue was still there after this fix or it's another one. Adding some more Cc's.
