AMD Radeon HD 7310/7340 [1002:9808]/[1002:9809] unable to resume from suspend with radeon driver

[Jeff Lane ]

While running 12.04.2 on an HP Pavilion dm1, the system is unable to resume from suspend while running the radeon driver.

The system successfully suspends, but on resume, the system starts waking and the screen does nothing but flash like a strobe light. The system had to be power-cycled to restore usability.

I put ubuntu 12.04 on a pos windows 8 laptop for a friend and the only problem I'm having is the one you describe. I've had "returning from suspend" work a few times on a fresh install, but after a day or to sitting in my apartment, it strobed again. I'll get some more info if it helps this report.

CID 201209-11793 (with [1002:9809]) could resume from suspend with RADEON driver in 12.04.3

[Po-Hsu Lin (cypressyew)]

Verified on 201208-11466 with [1002:9808]
This issue does not exist on 12.04.3
And this issue could be reproduced in 12.04.2 stock image.

However, after updated to 3.5.0-54, with xserver-xorg-core-lts-quantal upgraded from 2:1.13.0-0ubuntu6.1 to 2:1.13.0-0ubuntu6.5, it works, therefore I will mark this bug as Fix-released (verified on 201209-11793 and 201208-11466)

Please feel free to open a new bug if you're still experiencing this kind of issue, thanks!
