Title:
Filesystems end up remounted read-only
Status in linux package in Ubuntu:
Invalid
Bug description:
Sometimes (occasionally after resume, but also after just being left
alone for a while) my /home LV will become read-only.
This is a kern.log snippet from a case where I'd left it alone for a
few minutes:
