Well just a plain SCSI bus reset. Here is a sample:
kernel: scsi0 channel 0 : resetting for second half of retries. kernel: SCSI bus is being reset for host 0 channel 0. kernel: (scsi0:0:1:0) Synchronous at 40.0 Mbyte/sec, offset 15. kernel: (scsi0:0:3:0) Synchronous at 80.0 Mbyte/sec, offset 15. kernel: scsi0 channel 0 : resetting for second half of retries. kernel: SCSI bus is being reset for host 0 channel 0. kernel: (scsi0:0:1:0) Synchronous at 40.0 Mbyte/sec, offset 15. kernel: (scsi0:0:3:0) Synchronous at 80.0 Mbyte/sec, offset 15. kernel: sr1: CDROM not ready yet. last message repeated 3 times kernel: scsi0 channel 0 : resetting for second half of retries. kernel: SCSI bus is being reset for host 0 channel 0. kernel: (scsi0:0:1:0) Synchronous at 40.0 Mbyte/sec, offset 15. kernel: sr1: CDROM not ready yet.
I also tried reverting to the old aic78xx from 2.2.16 (aic 5.1.28) but it did not help (2.2.17pre* contains aic 5.1.31).
The wierd thing is that so far, only quake and quake2 have trouble playing CDs (with the uniform cd-rom driver 3.11). All other programs have no trouble at all.
