aic7xxx: waiting list inconsistency & spurious interrrupt errors

[Radhika Lal]

Hi :
I'm not subscribed to this mailing list but desperately need help.
I'm trying to install Redhat linux 5.0 (for this server we can't wait 
for 5.1 to come out) on the following :

Dell PowerEdge 2200
300MHZ PENTIUMr II dual  PROCESSOR  
Adaptec integrated SCSI aic7xxx controller
9GB ULTRA/WIDE SCSI-3 HARD DRIVE
12/24GB DDS-3 scsi TAPE BACKUP
CD-ROM DRIVE: 12/24X SCSI CD-ROM
3COM 3C905 10/100 Ethernet, PCI Adapter, 

Redhat 5.0 installation detects the scsi controller as 2940 and 
periodically I've been able to  complete the installation ok.
On other occasions when trying to read from the cdrom, the system  
crashes with the following message: kernel panic: aic7xxx waiting 
list inconsistency scb index 255, nubscbs=0 

On the occasion that I am able to complete the install, on rebooting, 
the machine goes into kernel panic again with a message about 
spurious interrupts and then aieeee: scheduling interrupt 000016... 
(I've unfortunately misplaced the sheet of paper with the exact 
message).

Thanks in advance
Radhika Lal
