Just a little FYI, I wanted to point out that 6.08 BETA fixed a problem I've been having since the 2.4.0-test series on a machine with the following adaptec integrated controller: Bus 4, device 7, function 0: SCSI storage controller: Adaptec 7899P (rev 1). IRQ 19. Master Capable. Latency=64. Min Gnt=40.Max Lat=25. I/O at 0x5000 [0x50ff]. Non-prefetchable 64 bit memory at 0xf7e00000 [0xf7e00fff]. Bus 4, device 7, function 1: SCSI storage controller: Adaptec 7899P (#2) (rev 1). IRQ 16. Master Capable. Latency=64. Min Gnt=40.Max Lat=25. I/O at 0x5400 [0x54ff]. Non-prefetchable 64 bit memory at 0xf7f00000 [0xf7f00fff].
This is an Ultra160 controller I believe (or at least thats what it says during bootup.)
Before I applied this patch it would print garbage for the Vendor/Rev/Type/ANSI SCSI revision of my hard disk. With this patch it does not.
I unfortunately know very little about SCSI drivers, so I can't say exactly what causes this problem with the stock 2.4.0 adaptec driver.
