Description of problem:
The current driver (aacraid) in RHEL 3 U4 (em64t) for ASR-2200s RAID adapter
does not function properly. It causes kernel panic during various operations.
Panic happens either during partitioning the drives or creating filesystems.
The latest driver available in 2.4.29 kernel fixes the issue.
Correcting kernel version.
> The latest driver available in 2.4.29 kernel fixes the issue.
That is a pretty huge diff. I would like to identify the particular fix for this
problem. Post any additional information you have on it.
Please post the console output showing the stack trace when the kernel panics.
RHEL 3 U5 is frozen. We will look at this for U6.
Unfortunately yes, it is a big diff. I'll try to get stack trace once I can
get the system back for this issue.

This is one of the dumps when system dies
I found a trace that I kept; not a helpful one though. The system oops in
various manners. I'll try to get other traces.

Another oops dump which happened during insmod
I tested the aacraid driver in RHEL 3 U6 Beta on ASR-2200S RAID adapter. I
was able to partition the drives, create filesystems and transfer files. The
Panic during insmod as described above didn't happen. I didn't see any
changes in the two drivers in U4 and U6. However, I did notice that when I
rmmod the driver and insmod the driver again, the driver stayed
at "initializing" state.
Correction: the OS build tested above was RHEL 3 U6 early release and not RHEL
3 U6 Beta.
Please test the kernel located at:
to verify that it solves the problem.
This contains version 1.1.5-2412 of the aacraid driver. This is the latest from
Adaptec, and is a candidate for U7.
Problem is solved in this test kernel rpm. Installed and removed module
several times without issue.
A fix for this problem has just been committed to the RHEL3 U7
patch pool this evening (in kernel version 2.4.21-37.10.EL).
This issue was found fixed with RHEL 3 U7 public beta. This bugzilla can be
Reverting to ON_QA state.
