Hi all,
I was wondering if someone knows how to debug this. I have a HP xw4300 PC with 2G RAM and 3GHz P4. Included is a
Promise EX8350 RAID card with 4 drives configured as RAID5. While doing some lengthy disk exercises (ie cp a 200G
directory of files) the kernel usually panics.
This is the 2.6.23 kernel patched to 2.6.24-rc4. The only module is the stex driver, all other drivers are in the kernel.
Can anyone debug this? (I am not a software guy) Do you need more info?
