Radeon: reserve failed for wait in /var/log/messages

Looking at my system log (kernel 2.6.35.4), this is a common thing:

Apr 24 12:04:49 kernel: radeon 0000:01:00.0: ffff8802d0aa1a00 reserve failed for wait
Apr 24 12:04:49 kernel: radeon 0000:01:00.0: ffff8802d0aa1a00 reserve failed for wait
Apr 24 12:04:51 kernel: radeon 0000:01:00.0: ffff8802d0aa1a00 reserve failed for wait
Apr 24 12:04:51 kernel: radeon 0000:01:00.0: ffff8802d0aa1a00 reserve failed for wait
Apr 24 12:04:57 kernel: radeon 0000:01:00.0: ffff8802d0aa1a00 reserve failed for wait
Apr 24 12:05:08 kernel: radeon 0000:01:00.0: ffff8802d0aa1a00 reserve failed for wait
Apr 24 12:05:14 kernel: radeon 0000:01:00.0: ffff8802d0aa1a00 reserve failed for wait

This doesn’t sound too good, but it looks like it’s harmless, according to this and this. It also looks like the decision was to remove the error message, rather than to fix something else. I suppose this issue is old news pretty soon.

It has been suggested that this error message appears only when compiz (that cool OpenGL toy making all kinds of effects on the desktop).

So just let it be.
