direct links of old sources may well be a few messages off.

I think (not 100% sure) that we did run wbtest on our SATA system
(without production load), and it did not trigger the problem.
Hmm, maybe we should try on the SATA system the versions of drbd and
kernel *exactly* same as on our high load SCSI systems that work well.
We already did it, and there where *some* problems but we did not
closely investigate them before upgrading.
