Hello Bernd, I'm reviewing this bug as part of the kernel bug triage project, an attempt to isolate current bugs in the fedora kernel. http://fedoraproject.org/wiki/KernelBugTriage I am CC'ing myself to this bug and will try and assist you in resolving it if I can. There hasn't been much activity on this bug for a while. Could you tell me if you are still having problems with the latest kernel? If the problem no longer exists then please close this bug or I'll do so in a few days if there is no additional information lodged. Cheers Chris
Sorry for the late response, but I've been on vacation for a while. kernel-2.6.22.9-91.fc7 still shows this messages. The system that I checked is FC7 fully updated. Also, the messages are not there every day, i.e. yesterday I had lots of them in /var/log/messages, but today I haven't found a single one yet.
I haven't looked at this yet, sorry. At first glance, a few explanations are possible: - An application is bombing HID through /dev/kbd or other means - Broken device which stalls control messages - A loop in kernel where up-stack events trigger controls (a kernel bug) - A race which causes the queue to get corrupt (a kernel bug) HID almost has no diagnostics at all, I really do not know what to do short of trying specially instrumented kernels. What is connected to the system? Please attach /proc/bus/usb/devices.

Bernd, Could I trouble you for an update? Are you still having this issue?
Seems to be fixed in the meantime. The system is now on F8 fully updated and I don't see such messages anymore.
