[ubuntu] optical drive errors

http://ubuntuforums.org – Nothing mission critical here, but a pretty annoying problem I've been having since the karmic beta. I've seen bug listings describing what I have been seeing but nothing identical, and all the proposed fixes have not been successful. My problem is this: Code: [15691.852615] ata3.00: status: { DRDY ERR } [15691.852625] ata3: hard resetting link [15692.382536] ata3: softreset failed (device not ready) [15692.382545] ata3: applying SB600 PMP SRST workaround and retrying [15692.562553] ata3: SATA link up 1.5 Gbps (SStatus 113 SControl 310) [15692.577454] ata3.00: SB600 AHCI: limiting to 255 sectors per cmd [15692.593301] ata3.00: SB600 AHCI: limiting to 255 sectors per cmd [15692.593307] ata3.00: configured for PIO0 [15692.593865] ata3: EH complete [15697.812542] ata3.00: qc timeout (cmd 0xa0) [15697.812573] ata3.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen [15697.812581] ata3.00: irq_stat 0x40000001 [15697.812601] ata3.00: cmd a0/00:00:00:00:00/00:00:00:00:00/a0 tag 0 [15697.812604]          cdb 00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00 [15697.812607]          res 51/20:03:00:00:00/00:00:00:00:00/a0 Emask 0x5 (timeout) This plugs up my dmesg output and I have problems seeing usb connects, disconnects, etc. It also appears in my tty's, just randomly making any output unreadable. I'm pretty sure this has to do with my dvd-rw drive on my laptop. edit: also worth noting, this doesn't happen when there is a disk present in the drive, otherwise it happens every 3 seconds.
