ON resume from hibernation, I get the GDM login, but it's just a gray rectangle with a white field in the middle. Cannot type into it and it doesn't respond to keyboards. Using SSH, accessed the system and found Xorg running at 100%. Killing Xorg allow access to system (with loss of saved session, of course). top - 08:36:37 up 7 min, 3 users, load average: 1.00, 0.82, 0.41 Tasks: 162 total, 2 running, 160 sleeping, 0 stopped, 0 zombie Cpu(s): 50.1%us, 0.2%sy, 0.0%ni, 49.6%id, 0.0%wa, 0.2%hi, 0.0%si, 0.0%st Mem: 2061508k total, 440320k used, 1621188k free, 25136k buffers Swap: 4112376k total, 0k used, 4112376k free, 218200k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1895 root 20 0 90240 27m 7968 R 100.2 1.4 3:10.79 Xorg pstack 1895 #0 0x00fdef0d in nouveau_dma_wait () from /usr/lib/libdrm_nouveau.so.1 #1 0x00fdd132 in nouveau_pushbuf_flush () from /usr/lib/libdrm_nouveau.so.1 #2 0x003be659 in NV04EXAUploadIFC () #3 0x003a1dad in ??

Since this bugzilla report was filed, there have been several major updates in various components of the Xorg system, which may have resolved this issue. Users who have experienced this problem are encouraged to upgrade their system to the latest version of their packages. For packages from updates-testing repository you can use command yum upgrade --enablerepo='*-updates-testing' Alternatively, you can also try to test whether this bug is reproducible with the upcoming Fedora 12 distribution by downloading LiveMedia of F12 Beta available at http://alt.fedoraproject.org/pub/alt/nightly-composes/ . By using that you get all the latest packages without need to install anything on your computer. For more information on using LiveMedia take a look at https://fedoraproject.org/wiki/FedoraLiveCD . Please, if you experience this problem on the up-to-date system, let us now in the comment for this bug, or whether the upgraded system works for you. If you won't be able to reply in one month, I will have to close this bug as INSUFFICIENT_DATA. Thank you. [This is a bulk message for all open Fedora Rawhide Xorg-related bugs. I'm adding myself to the CC list for each bug, so I'll see any comments you make after this and do my best to make sure every issue gets proper attention.]
Steven, if you update your system per Comment #2, is this still an issue for you? -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
Due to a disk crash, I no longer have this system available.
