For what it's worth, I'm seeing this now as well (I first noticed Friday night
Oct 23). Last system update was Oct 21 (and now Oct 24, to see if there was
anything that fixed this). Before that was -current from Oct 10, which did
not seem show these symptoms (there was only a one-line change.. Hm..).
The only thing on that bus is my CD-R:
ncr0: <ncr 53c875j fast20 wide scsi> rev 0x04 int a irq 11 on pci0.13.0
cd0 at ncr0 bus 0 target 5 lun 0
cd0: <MATSHITA CD-R CW-7502 4.10> Removable CD-ROM SCSI2 device
cd0: 10.0MB/s transfers (10.0MHz, offset 8)
cd0: Attempt to query device size failed: NOT READY, Medium not present - tray closed
And this error message
ncr0: SCSI phase error fixup: CCB already dequeued (0xf0a53400)
ncr0: timeout nccb=0xf0a53400 (skip)
...
ncr0: timeout nccb=0xf0a53400 (skip)
(cd0:ncr0:0:5:0): lost device
(cd0:ncr0:0:5:0): removing device entry
ncr0: timeout nccb=0xf0a53400 (skip)
...
After quite a while (hours), it eventually "resets" and is usable again. I
notice there is at least one (audio) CD that will trigger this behavior 100% of
the time.
