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) start udev daemon # udevd set the logging level # udevadm control --log-priority=info start the monitor # udevadm monitor ... see change events... <ctrl>-<c> # killall udevd # grep udev /var/log/messages > udev.log and attach udev.log in this bugzilla. udev.log attached to the bug Created attachment 369855 [details]
udev.log
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 Created attachment 369864 [details]
output from the while loop
doh! I am sorry.. got the number wrong.. log is full of error messages.. please again with # while true; do lsof +c 15 /dev/dri/card0;done There is the file :) Created attachment 369869 [details]
output from the 2nd while loop
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. |
