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:

This looks similar to an issue followed on this linux-kernel thread:
http:// marc.info/ ?t=123795843900 001&r=1& w=2
Please open a bug in the kernel bugzilla (http:// bugzilla. kernel. org) to track this issue. When a fix is found upstream we may be able to pull the fix into Ubuntu.
Thanks
