My dmesg looks looks like this:
FreeBSD 2.2-ALPHA #0: Wed Nov 13 15:29:19 1996
jkh@time.cdrom.com:/usr/src/sys/compile/GENERIC
Calibrating clock(s) relative to mc146818A clock ... i586 clock:

ahc0 <Adaptec 2940 Ultra SCSI host adapter> rev 0 int a irq 11 on pci1:9
ahc0: aic7880 Wide Channel, SCSI Id=7, 16 SCBs
ahc0 waiting for scsi devices to settle
(ahc0:0:0): "SEAGATE ST32550N 0019" type 0 fixed SCSI 2
sd0(ahc0:0:0): Direct-Access 2047MB (4194058 512 byte sectors)
ahc0:A:5: refuses WIDE negotiation. Using 8bit transfers
(ahc0:5:0): "NEC CD-ROM DRIVE:462 1.14" type 5 removable SCSI 2
cd0(ahc0:5:0): CD-ROM cd present [285226 x 2048 byte records]
[...]
in 2.2-SNAP the problem was so bad it would lock up the machine. However,
what is this with the 8bit transfers? I have the sneaking feeling
this is the reason why my cd-device may not be work working well with
audio cd's (even with "cdplayer" !!). Atleast with 2.2-ALPHA things
are better... but then, OK, I understand.. it *is* ALPHA :)
Anyone looking into this?
