The problem is when some of these drivers are just not smart
enough to keep themselves out of trouble. Unfortunately I've
been bitten by apparently too many of them.
I'll repeat my plea one more time. Is there a published list
of tested combinations that respond well to hardware failures
and fully signals the md code so that nothing hangs?
If not, I would like to see what people that have experienced
hardware failures and survived them are using so that such
a list can be compiled.
