DRI applications hang after DPMS standby on i965

Bug #848687 reported by Evan Broder on 2011-09-13

Affects Status Importance Assigned to Milestone
linux (Ubuntu)

Bug Description

SRU Justification:

Impact: When multiple DRI applications are running on an i965, and the screen goes into standby, one of the applications will sometimes hang when the screen is woken back up. Sometimes this occurs with compiz, which renders the desktop unusable. In at least one case, the hang was in DRI2GetBuffersWithFormat, though I don't know that that's consistent.

Fix: Bisected e8e7a2b8ccfdae0d4cb6bd25824bbedcd42da316 as fix from upstream kernel

Testcase: While using Unity, run "glxgears &" and "xset s 1". Continue to wake up the screen when it goes into standby. On affected hardware, either glxgears or compiz (i.e. the whole desktop) will eventually hang

This bug is awaiting verification that the kernel for Natty in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-natty' to 'verification-done-natty'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

I was unable to reproduce the hang using the kernel from -proposed.
