I'm using ide-scsi, so this is an iso9660 filesystem mounted from /dev/scd0. After reading for a while, apparently successfully, it started failing with the messages below: spurious 8259A interrupt: IRQ7. hdc: lost interrupt ide-scsi: CoD != 0 in idescsi_pc_intr ide-scsi: abort called for 9677 ide-scsi: abort called for 9674 hdc: ATAPI reset complete hdc: irq timeout: status=0x80 { Busy } hdc: ATAPI reset complete hdc: irq timeout: status=0x80 { Busy } hdc: ATAPI reset complete hdc: irq timeout: status=0x80 { Busy } hdc: status timeout: status=0x80 { Busy } hdc: drive not ready for command hdc: ATAPI reset complete hdc: irq timeout: status=0x80 { Busy } hdc: ATAPI reset complete hdc: irq timeout: status=0x80 { Busy } hdc: status timeout: status=0x80 { Busy } hdc: drive not ready for command hdc: ATAPI reset complete hdc: irq timeout: status=0x80 { Busy } hdc: ATAPI reset complete hdc: irq timeout: status=0x80 { Busy } hdc: status timeout: status=0x80 { Busy } hdc: drive not ready for command hdc: ATAPI reset complete hdc: irq timeout: status=0x80 { Busy } hdc: ATAPI reset complete hdc: irq timeout: status=0x80 { Busy } hdc: status timeout: status=0x80 { Busy } hdc: drive not ready for command hdc: ATAPI reset complete ide-scsi: abort called for 9674 ide-scsi: abort called for 9675 ide-scsi: abort called for 9676 ide-scsi: reset called for 9677 ------------[ cut here ]------------ kernel BUG at kernel/timer.c:155! invalid operand: 0000 [#1] CPU: 0 EIP: 0060:[] Tainted: PF EFLAGS: 00010002 EIP is at add_timer+0xdb/0xe8 eax: 00000001 ebx: c1b3b5e4 ecx: c0322820 edx: c03d33fc esi: 00000096 edi: c020b506 ebp: f7d8feac esp: f7d8fea4 ds: 007b es: 007b ss: 0068 Process scsi_eh_0 (pid: 9, threadinfo=f7d8e000 task=c1b7cd00) Stack: 00000001 c1b3b5c0 f7d8fed0 c020b44c c1b3b5e4 00000000 00000082 00000000 00000000 c03d33fc c03d33fc f7d8ff00 c020baf4 c03d33fc c020b506 00000032 00000000 c1b3b5c0 c03d3350 00000096 00000000 c03d33fc c03d340c f7d8ff18 Call Trace: [] ide_set_handler+0x48/0x74 [] do_reset1+0x214/0x232 [] atapi_reset_pollfunc+0x0/0x11a [] ide_do_reset+0x2e/0x62 [] idescsi_reset+0xc0/0xf6 [] scsi_try_bus_device_reset+0x46/0x66 [] scsi_eh_bus_device_reset+0x65/0x108 [] scsi_eh_ready_devs+0x28/0x74 [] scsi_unjam_host+0xa1/0xa4 [] scsi_error_handler+0xad/0xdc [] scsi_error_handler+0x0/0xdc [] kernel_thread_helper+0x5/0xc Code: 0f 0b 9b 00 62 11 2e c0 e9 41 ff ff ff 55 31 c0 89 e5 83 ec
