Created attachment 369838 [details] output from udevmonitor Description of problem: After a while (sometimes it is from the beginning) it seems that udev is crashing my machine Version-Release number of selected component (if applicable): udev-145-12.fc12.x86_64 How reproducible: always Steps to Reproduce: 1. boot 2. wait for a while 3. crash Actual results: Computer really, really slow When I kill udevd it comes back to life Expected results: working normally from the beginning Additional info: Attached is the output of udevmonitor > udevmonitor.txt run while the computer was crashing
Something is opening the drm device with the write flag and closes it. This causes a change event. Seems like the same thing is triggered by it. Can you identify what it is? Boot with "udevinfo" and /var/log/messages should contain the info.
I see a: Nov 17 08:33:14 localhost kernel: [drm:drm_mode_rmfb] *ERROR* tried to remove a fb that we didn't own Nov 17 08:33:14 localhost kernel: [drm:drm_mode_rmfb] *ERROR* tried to remove a fb that we didn't own in /var/log/messages Regarding udevinfo it says that I should use udevadm info <options> however I don't have any clue what option I shoud use, any hint ?
ok so I log into root, start udevd command line: I run tail -f on /var/log/message, it gave the following output: Nov 17 11:02:10 localhost kernel: udev: starting version 145 Nov 17 11:02:55 localhost udevadm[9070]: the program '/bin/bash' called 'udevmonitor', it should use 'udevadm monitor <options>', this will stop working in a future release I run udevmonitor which again gave a bunch of: UDEV [1258452193.190305] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) UDEV [1258452193.191538] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) KERNEL[1258452194.513870] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) KERNEL[1258452194.514843] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) UDEV [1258452194.515617] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm) UDEV [1258452194.520309] change /devices/pci0000:00/0000:00:02.0/drm/card0 (drm)

hmm.. reminds me of bug #528312
can you run: # while true; do lsof +c 16 /dev/dri/card0;done for a while (while udevd is looping) and post the output?
output from the while loop attached

There is the file :)

ok, so I see only firefox and Xorg (the X server) have this file open.. I guess, it's bug 528312 .. so I will close this bug, and you will be attached to the other bug automatically. *** This bug has been marked as a duplicate of bug 528312 ***
Thanks for your help.
