I'm running FreeBSD current (ctm 1849) and the CD-ROM hangs the system
after few seconds of disk access producing the following on the console:

Jun  5 10:36:21 socrate /kernel: cd0(ahc0:3:0): timed out in dataout
phase, SCSISIGI == 0x48
Jun  5 10:36:21 socrate /kernel: cd0(ahc0:3:0): timed out in dataout
phase, SCSISIGI == 0x48
Jun  5 10:36:30 socrate /kernel: cd0(ahc0:3:0): BUS DEVICE RESET message
queued.
Jun  5 10:36:30 socrate /kernel: cd0(ahc0:3:0): BUS DEVICE RESET message
queued.
Jun  5 10:36:33 socrate /kernel: Bus Device Reset Message Sent
Jun  5 10:36:33 socrate /kernel: Bus Device Reset Message Sent

 The only way to get out of this is to shut the system down...

 I belive it's a software problem as:
1) the CD-ROM works under two other operting systems on the same machine
2) the CD-ROM works with 2.2 kernel.GENERIC

 Anyway my machine is configured as follows:
 - Controller SCSI Adaptech 2940 U/UW bios v1.21
 - HD SCSI Wide Seagate ST32550W (connected to the wide connector)
 - CD-ROM SCSI-II Sony CDU 76-S (connected to the standard connector)

 May this be due to actual VM problems? If not should I argue there's a
bug in the ahc controller?
