Bug ID: 90623
Summary: Intel GPU hangs on resume from suspend - screen
freezes, must hard reboot
Product: DRI
Version: XOrg git
Hardware: Other
OS: other
Status: NEW
Severity: major
Priority: medium
Component: DRM/Intel
Assignee: intel-gfx-bugs at lists.freedesktop.org
Reporter: rahulk at yandex.com
QA Contact: intel-gfx-bugs at lists.freedesktop.org
CC: intel-gfx-bugs at lists.freedesktop.org
Possible duplicate bug: https://bugs.launchpad.net/elementaryos/+bug/1404826,
although my issue has nothing to do with firefox. The problem occurs more
frequently when I manually suspend the session and try to resume. I've got
nothing special on resume from suspend as far as I can tell. Filing bug here
because the /var/log/syslog entry asked me to.
