Okay, the one-liner eh fix for libata appears to prevent
the lockups here, so I will continue using it from now on
in place of the earlier more complex patch.

And it looks "obviously correct" too, a Good Thing (tm).

Jeff:   This one should go out ASAP.

Tejun:  I'm short on time to soak the other larger patch,
as the problem occurs only on my primary notebook PC,
and I really need it for "real (paid) work" now.

Cheers
