Additional info:

I did change video driver to VESA in xorg.conf and this issue disappeared. So with VESA driver I do not have this freezes.
Also I added i915.powersave=0 which does not help with intel driver.

Thanks for the bug report.  We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue.

Please add drm.debug=0x04 to the kernel command line, restart computer, and attach

* your X server config file (/etc/X11/xorg.conf, if available),
* X server log file (/var/log/Xorg.*.log)
* output of the dmesg command, and
* system log (/var/log/messages)

to the bug report as individual uncompressed file attachments using the bugzilla file attachment link above.

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.

It happens every 10 seconds, I found it out with stopwatch.
Comment 8 Matěj Cepl 2010-10-20 13:44:37 UTC 
Try to run as root before it happens

udevadm monitor --env 2>&1|tee udevadm-monitor-log.txt

and then wait until the event strikes, wait through it, and attach here complete udevadm-monitor-log.txt.

I wonder whether this isn't just another occurrence of bug 528312, it seems to be alive lately.

Thank you
Comment 9 sd.domrep 2010-10-20 18:37:04 UTC 
udevadm monitor --env 2>&1|tee udevadm-monitor-log.txt gave nothing after 10 minutes.
Comment 10 sd.domrep 2010-10-31 08:28:16 UTC 
OK, I would like to help you a little bit.

I found out what is happening when my mouse cursor freezes:
[drm:intel_crtc_cursor_set], 
[drm:intel_crtc_cursor_set], cursor off
...
[drm:intel_crtc_cursor_set], 
[drm:intel_crtc_cursor_set], cursor off
...
from dmesg with drm.debug=0x04
Comment 11 sd.domrep 2010-11-03 14:04:46 UTC 
You know, I am confused.

1. The component was changed to "xorg-x11-server" from "xorg-x11-drv-intel", but I do not have this issue with vesa driver, which the same x11 server.

2. Chris Wilson from "intel-gfx" told me that with is:
..."Known issue with "hotplug" polling on those systems:
https://bugs.freedesktop.org/show_bug.cgi?id=29536"...

And now I am waiting for patched drm_kms_helper kernel 2.6.35, because I can't disable polling in 2.6.35 on Fedora 14.

Please explain me something if possible.
Thanks.

Problem solved in kernel:
2.6.35.8-55.fc14.i686.PAE #1 SMP Fri Nov 12 04:57:24 UTC 2010 i686 i686 i386 GNU/Linux

no matter if POLL=Y or N, I do not have this freezes.

This bug may be closed.

Thanks.
