Probs with the aic7xxx on an AIC7895

[Knoblach Peter]

Hi there,

I have problems booting the aic7xxx with the new SuSE 6.1:
When I boot form the CD and load the aic7xx module I get the folowing
message:

(scsi0:-1:-1:-1) Referenced SCB 255 not valid during SELTO.
        SCSISEQ = 0x5a SEQADDR = 0x7 STATO =0x10 SSTAT1 = 0x88


------------------ My Hardware:
Board: IWILL BS100 with AIC7895 (UW DUAL CHANEL Board Chip Set)

Booten the SuSE 6.0 fails too. The same messages appeaers.

I have probed several things. 
Lower down the max speed in the SCSI BIOS: the same
Disconecting the first HD from the first chanel: the same
Disconecting all the devices from both chanel: the same

Someone was speaking about a bootimage name "scsi01" on ftp.suse.com in the
newsgroups
that should solve the Problem. So I 've downloaded this one and booted with
it.
The only diference are more detailed messages:

(scsi0:-1:-1:-1) Referenced SCB 255 not valid during SELTO.
        SCSISEQ = 0x5a SEQADDR = 0x7 STATO =0x10 SSTAT1 = 0x88

        SCSISEQ = 0x5a SEQADDR = 0x8 STATO =0x10 SSTAT1 = 0x88
                        ...           ...
                        ... and so on ...

              	     ... then appears ...
SCSI host 0 chanel 0 reset (pid 0) timed out - trying harder
SCSI bus is being reset for host 0 chanel 0

              		  ... and ...
(scsi0:0:-1:-1) Waiting List inconsistency; SCB index = 255 numscbs = 15
(scsi0:0:-1:-1) Yikes!! There is a loop in the waiting for the selection
list!

An old SuSE 5.2 CD1 let me boot linux and the aic7xxx is working fine:

I send the problem to the SuSE support.
But..
(1) I think there are others out there who have the same problems.
(2) I am now in that situation where I whant to know the why and not only a
new
    boot image that solves the install problem. (I whant to build my own
kernel)

Thx,

Peter Knoblach
