I haven't seen the error happen yet with 2.6.27-rc6-git3, so that off
by one bug might have had an incidence.
No warranty on that as I did also slightly change power-saving settings
for the disk around the time I updated kernel (-B254, -S241 parameters
to hdparm) and have not seen the error yet on 2.6.27-rc5-git9 since
then.

Will do more testing as time permits over the next days and report if I
find anything that looks useful (e.g. better way than time to trigger
the error or some of the hdparm options influencing the probability)

In case there is a patch that would eventually be able to get more info
when the error occurs I would be happy to apply it.
