Random IDE Lock ups with via IDE

[Jim Gifford <maillist@jg555.com>]

I have been using the 2.6.10.x series kernel for a while on my other 
systems with no issues at all.

But on my laptop which has the via 686 chipset, I started having some 
wierd issues. This happens after about 2 weeks of non-shutting down

Here is a sample of the data from my kernel log
