Subject: Commit 35ce7f29a breaks hibernation for XPS 13
Date: Fri, 24 Oct 2014 12:08:15 -0400 [thread overview]
Message-ID: <20141024160815.GA2968@akamai.com> (raw)
Paul,
As of 3.18-rc1 I can no longer hibernate my Dell XPS-13. Bisect points
the finger at 35ce7f29a. A revert of that commit confirms, I can once
again hibernate my machine without it.
When the hibernation fails I see this in dmesg:
[ 37.953313] PM: Syncing filesystems ... done.
[ 37.963694] Freezing user space processes ... (elapsed 0.001 seconds) done.

I am not sure what else I can provide that might be useful, but I did
see the thread on net-dev about this same commit. Please CC me on any
fixes and I will be happy to test.
Eric
