-update

Sometimes after many hours is quite uncertain, but since Mar 25 snapshot
I didn't see it again on md9717 with a new kernel config.

Also this complete losses (seen on 0.2.6) I had got rid of by disabling
apic on UP (A7V133 KT133A).

In the README for the new nvidia driver 1.0-4349 is mentioned now, that
apic enabled may influence system stability on some hardware ...
