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
What is the resolution to this issue?
Version-Release number of selected component (if applicable):
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
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?)
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.
No reply in over a year. The current AS 2.1 errata has aic79xx v1.3.10.
Assuming this fixed the problem.
