Thanks for the report. I'll try to come up with a patch to reduce
the severity of overruns to something less than HSM.

I'd like to see that too.
No such HSM error messages or any EH invocation with the sata-via on 2.6.32.2 :-)
Nor on growisofs startup or dvdrw drive servo failure like it occured with sata-promise.
