Re: [PLUG] Hard Drives Crashing

I can confirm that I have had similar hardware smp/aic7xxx as well as
similar crash messages. So I can confirm this.

I have updated the kernel (rh's latest) and things are going well. But
things were ugly for a while.

I have read that smp/aic7xxx/ext3 don't play well, somewhere on the
kernel mailing list. I think that the latest patches iron those bugs out.

We have not had a problem since upgrading. I upgraded again to
2.4.18-24.7.xsmp and we have really nice uptimes.

Good luck with this. It can be hair raising.
