Hello! I tried killing some processes but it didn't help. I also attatched gdb to the Xorg process but gdb just hanged and wouldn't produce a backtrace, even if I ran "killall Xorg" or "killall -9 Xorg" from another ssh session. It seems impossible to stop the Xorg process once it gets into this state.
Anyway, I just discovered an error in kern.log. It looks similar to bug #881526. That bug isn't about suspend/resume issues but I guess it could be the same problem. I also guess there isn't much to do about this then except waiting for AMD to fix it. :( Apr 11 18:40:38 simon-305U1A kernel: [ 416.884015] [fglrx] ASIC hang happened Apr 11 18:40:38 simon-305U1A kernel: [ 416.884029] Pid: 1049, comm: Xorg Tainted: P O 3.2.0-23-generic #36-Ubuntu Apr 11 18:40:38 simon-305U1A kernel: [ 416.884033] Call Trace: Apr 11 18:40:38 simon-305U1A kernel: [ 416.884147] [<ffffffffa00d4ffe>] KCL_DEBUG_OsDump+0xe/0x10 [fglrx] Apr 11 18:40:38 simon-305U1A kernel: [ 416.884196] [<ffffffffa00e258c>] firegl_hardwareHangRecovery+0x1c/0x50 [fglrx] Apr 11 18:40:38 simon-305U1A kernel: [ 416.884281] [<ffffffffa017e119>] ? _ZN4Asic9WaitUntil15ResetASICIfHungEv+0x9/0x10 [fglrx] Apr 11 18:40:38 simon-305U1A kernel: [ 416.884360] [<ffffffffa017e0bc>] ? _ZN4Asic9WaitUntil15WaitForCompleteEv+0x9c/0xf0 [fglrx] Apr 11 18:40:38 simon-305U1A kernel: [ 416.884440] [<ffffffffa01813cc>] ? _ZN8AsicR60012IO_QuietdownEv+0x2c/0x40 [fglrx] Apr 11 18:40:38 simon-305U1A kernel: [ 416.884520] [<ffffffffa0178bd4>] ? _ZN15ExecutableUnits10CPRingIdleE15idle_WaitMethod12_QS_CP_RING_+0x134/0x1e0 [fglrx] Apr 11 18:40:38 simon-305U1A kernel: [ 416.884600] [<ffffffffa0178a4c>] ? _ZN15ExecutableUnits7PM4idleE15idle_WaitMethod+0x4c/0x90 [fglrx] Apr 11 18:40:38 simon-305U1A kernel: [ 416.884678] [<ffffffffa01785b6>] ? _ZN15ExecutableUnits9assertPM4Eb+0x56/0x70 [fglrx] Apr 11 18:40:38 simon-305U1A kernel: [ 416.884756] [<ffffffffa0182959>] ? _ZN8AsicR6009assertPM4Eb+0x39/0x80 [fglrx] Apr 11 18:40:38 simon-305U1A kernel: [ 416.884809] [<ffffffffa0101550>] ? firegl_cmmqs_disabledriver+0xf0/0xf0 [fglrx] Apr 11 18:40:38 simon-305U1A kernel: [ 416.884876] [<ffffffffa0150d65>] ?
