Description Matt Dralle 2003-01-08 21:32:01 UTC

User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; Q312461; .NET 
CLR 1.0.3705)

Description of problem:
Server and a SuperMicro dual-cpu 2.8ghz, hyperthreading motherboard with a 
Ultra320 SCSI controller built on.


Note that it says that "Red Hat is aware of the issue and is working on a fix 
for it"...

What is the resolution to this issue?

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Boot the system

Actual Results:  About half way through the boot process, the kernel reports 
panic and that it can't find something about 8,1 and that the user should add a 
boot= line to somethign.

Expected Results:  Boot completes

Additional info:

The Adaptec website indicates that this is a "known issue" within Red Hat an 
that they are working on a fix.

Installing a PCI 2940u2 SCSI card in the system and putting the boot disk on it 
will result in the system booting fine.  i.e. the problem is definately related 
to the 320 SCSI controller (aic79xx?)

Comment 2 Tom Coughlan 2003-07-25 20:47:54 UTC
The early versions of the aic79xx driver had many problems.  The aic79xx driver
rev. 1.3.4 in the latest AS2.1 kernel errata (e.25) may solve the problem.  If
not, there is a newer rev. 1.3.10 available from the maintainer 


We plan to update this driver in the next AS 2.1 errata.

Comment 3 Tom Coughlan 2004-08-25 14:29:07 UTC
No reply in over a year.  The current AS 2.1 errata has aic79xx v1.3.10. 
Assuming this fixed the problem.
