Our working hypothesis for a workaround is to do as follows:
In afacli, set:
Read Cache: enabled
Write Cache: enabled when protected
Then unplug the ROMB battery. A reboot is not necessary. The
firmware will immediately drop into Write-Through Cache mode, which in
our testing has not exhibited the problem. Setting the write cache to
disabled in afacli doesn't seem to help - you've got to unplug the
battery with it in the above settings.
We are continuing to search for the root cause to the problem, and
will update the list when we can.
