Right, let me try that and report back.

Yep, looks like reverting the above commit fixes it - the
website loads just fine.



Saw the same error and after reading this thread, reverted the

Commit 2d6cc7296d4ee128ab0fa3b715f0afde511f49c2.

drm/radeon: use async dma for ttm buffer moves on 6xx-SI

and the problem is gone. In my case, it is a solid hang right after
system switches to vga. I was able to login on console once or twice.
But dmesg showed the same message reported in this thread:

[ 35.812085] radeon 0000:01:00.0: GPU lockup CP stall for more than 10000msec
[ 35.812091] radeon 0000:01:00.0: GPU lockup (waiting for
0x0000000000000002 last fence id 0x0000000000000001)

My system has:
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee
ATI RV620 [Mobility Radeon HD 3400 Series]

I ended up also that same commit after bisecting from current 3.8 master.

01:05.0 VGA compatible controller: ATI Technologies Inc 760G [Radeon 3000]
It is ASUS M5A78L-M/USB3 with integrated GPU.

I cannot even boot unless graphical boot is removed from Fedora 17 boot options (rhgb quiet). Random GPU crashes still.
