Greetings,
I've been using the new aic7xxx driver, and updating frequently from Justin's site. I'm at v6.1.11 now with kernel 2.4.3 and still experiencing some odd behaviour. For example, I start as such on BUS 0 (an aic-29160):
Channel A Target 5 Negotiation Settings
User: 160.000MB/s transfers (80.000MHz DT, offset 255, 16bit)
Goal: 160.000MB/s transfers (80.000MHz DT, offset 63, 16bit)
Curr: 160.000MB/s transfers (80.000MHz DT, offset 63, 16bit)
Channel A Target 5 Lun 0 Settings
Commands Queued 13199
Commands Active 0
Command Openings 49
Max Tagged Openings 253
Device Queue Frozen Count 0
After an invocation of cdrecord --scanbus
dmesg reveals this on BUS1 (an aha-2940u2w):
(scsi1:A:1): 5.000MB/s transfers (5.000MHz, offset 15)
(scsi1:A:6): 20.000MB/s transfers (20.000MHz, offset 15)
(locating burner at 6, and zip at 5)
An invocation of hdparm -Tt /dev/sda (id 5) does this:
(scsi1:A:1): 5.000MB/s transfers (5.000MHz, offset 15)
(scsi1:A:6): 20.000MB/s transfers (20.000MHz, offset 15)
(scsi0:A:5): 3.300MB/s transfers
cat /proc/scsi/aic7xxx/0 :
Channel A Target 5 Negotiation Settings
User: 160.000MB/s transfers (80.000MHz DT, offset 255, 16bit)
Goal: 3.300MB/s transfers
Curr: 3.300MB/s transfers
Channel A Target 5 Lun 0 Settings
Commands Queued 16817
Commands Active 0
Command Openings 49

Device Queue Frozen Count 0
Target 5 has dropped to 3.300MB/s ??
thanks,
Ethan W.
