It doesn't seem to cause any instabilities or failures, but still. It also can be interesting that these errors were printed very often when I tried ivd/rt2x00.git and wifi interface was up.

Have you tried 2.6.32-rc3?

2.6.32-rc1 included an important rewrite for the "EmbeddedControl" (EC) driver. It was reported that this caused timeouts on some machines. These specific timeouts were then fixed in -rc3. So it would be interesting to see how -rc3 affects the timeout messages you are seeing.

Thanks
Alan.

I've already built it, so if that exceptions will show again with .32, I'll report.
