constant kernel message: [drm:drm_wait_vblank] *ERROR* failed to acquire vblank counter, -22

[satmandu]

I these messages constantly in dmesg, and in kern.log:
Jul 11 19:04:39 dellmini9 kernel: [ 1145.712280] [drm:drm_wait_vblank] *ERROR* failed to acquire vblank counter, -22

I'm assuming that this is related to the video drivers, but I'm not sure what I should do to make this stop.

[This is an automated message. Apologies if it has reached you inappropriately.]

This bug was reported against the linux-meta package when it likely should have been reported against the linux package instead. We are automatically transitioning this to the linux kernel package so that the appropriate teams are notified and made aware of this issue.

If this bug really is a bug in the linux-meta package you can move it back to linux-meta and set the Status to Confirmed, or contact us on the #ubuntu-kernel channel on the FreeNode IRC server. Thanks.

I also get a lot of these errors under Karmic alpha-3 (UNR) with a HP Mini 1000 (1120NR). Confirming this bug report.

[Stuart Read (sread)]

Based on the Fedora comments, this sounds like a bug specific to the DRM used in the intel graphics driver.

[Bryce Harrington (bryce)]

It is harmless, and it is in the kernel drm code, so no need for a task against -intel.

[Jamie (jtroybailey)]

I also get this on an Asus EEE PC 901
