Exit the DVD

Hot removing an IDE DVD drive from  Linux box looks something like the following in the /var/log/messages file.

... Jun 16 14:15:09 <system_name> kernel: hdb: ATAPI reset complete Jun 16 14:15:09 <system_name> kernel: hdb: status error: status=0x00 { } Jun 16 14:15:09 <system_name> kernel: ide: failed opcode was: unknown Jun 16 14:15:09 <system_name> kernel: hdb: status error: status=0x00 { } Jun 16 14:15:09 <system_name> kernel: ide: failed opcode was: unknown Jun 16 14:15:09 <system_name> kernel: hdb: status error: status=0x00 { } Jun 16 14:15:09 <system_name> kernel: ide: failed opcode was: unknown Jun 16 14:15:09 <system_name> kernel: hdb: status error: status=0x00 { } Jun 16 14:15:09 <system_name> kernel: ide: failed opcode was: unknown Jun 16 14:15:09 <system_name> kernel: hdb: ATAPI reset complete Jun 16 14:15:09 <system_name> kernel: hdb: status error: status=0x00 { } Jun 16 14:15:09 <system_name> kernel: ide: failed opcode was: unknown Jun 16 14:15:09 <system_name> kernel: hdb: status error: status=0x00 { } Jun 16 14:15:09 <system_name> kernel: ide: failed opcode was: unknown Jun 16 14:15:09 <system_name> kernel: hdb: status error: status=0x00 { }

And then the mouse is choppy. The system tries to poll the IDE buss and find the drive that is no longer there. There is some kind of IRQ magic going zapping the system in the background.

Still had to reboot.
