Ok, with a refined test I've been able to reliably reproduce this and I
bisected it back to commit 85ef06d1d252f6a2e73b678591ab71caad4667bb in
Linus' tree (introduced between 3.0 and 3.1):
commit 85ef06d1d252f6a2e73b678591ab71caad4667bb
Author: Tejun Heo <tj@xxxxxxxxxx>
Date: Fri Jul 1 16:17:47 2011 +0200
block: flush MEDIA_CHANGE from drivers on close(2)
Prior to the above commit, sleeping disks will spin up as a result of
I/O sent to them. With the above commit, they don't spin up and
immediately return an I/O failure.
That's all the further I've gotten so far. I'll be happy to test any
patches or suggestions.
