<sigh> where to start,..

I have a system which has an onboard aic79xx controller

lspci -vv :

Ok, to the problem itself. I've found that the system will choke badly after
anything from a few days to a couple of weeks, always over a LQI Phase error.
I've asked around to help work out what the LQI Phase error is about and
I still don't understand it.

When the system is up and running, the disk is stable and I
get a quite respectable 72MB/s max throughput.

I have other card dumps however since this isn't my area of expertise I've
not included them as they're roughly the same problem always starting off
with a "Reseting Channel for LQI Phase error" error.

I should mention that I have a sister machine with the exact same HW 
that exhibits the issues and though not a 100% indication, it
would suggest the issue is more to do with the driver.

I did also try to rebuild the kernel with aic79xx-linux-2.6-20040522-tar.gz
however I've not run it long enough on the box to say that it fixes the issue

Ideas anyone? or shall I just keep banging on 2.0.12 and hope it fixes/masks
the problem?

Phil
