Hi All,

We did a full raid resync, with e2fsck and was still able to get another OOPS after about a week of running "stress".

Unfortunately this report didn't get everything, but hopefully its still helpful.

The kernel version is the same as Fedora 12 hasn't yet released an update.

Thanks,

Rusty
