Bug#752916: linux-image-3.14-1-amd64: btrfs error after USB device goes to sleep (super.c:257 and extent-tree.c:134)
Package: src:linux
Version: 3.14.7-1
Severity: normal
Tags: upstream
Dear Maintainer,
I have an USB disk that turns off automatically after a certain time of inactivity
(but that is another problem), and when this happens, accesses to the (still) mounted
filesystem leads to the messages stated below in the kernel log.
Although I do not expect miracles there, I would tend to think that upstream may
appreciate the feedback to provide a saner behaviour to handle that situation.
On a side note, I did a quick check on changelogs in kernel.org and have not seen
any commit that would help in 3.14.8 and 3.14.9. I made light cleanup in the stuff
below to try to keep only what would be relevant.
Regards,
Christophe.
