Red Hat Bugzilla – Bug 250005
Lots of USB control queue full messages
Last modified: 2008-01-10 14:21:37 EST
Description of problem:
I'm seeing lots of these messages in /var/log/messages:
Jul 28 19:28:57 riker kernel: drivers/hid/usbhid/hid-core.c: control queue full
Jul 28 19:29:40 riker last message repeated 4 times
Jul 28 19:30:49 riker last message repeated 4 times
Jul 28 19:32:09 riker last message repeated 8 times
Jul 28 19:33:29 riker last message repeated 8 times
Jul 28 19:34:30 riker last message repeated 6 times
I notice these messages at least since kernel-18.104.22.168-27.fc7 and they are still
Version-Release number of selected component (if applicable):
Steps to Reproduce:
I'm reviewing this bug as part of the kernel bug triage project, an attempt to
isolate current bugs in the fedora kernel.
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.
Sorry for the late response, but I've been on vacation for a while.
kernel-22.214.171.124-91.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
- 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.

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.

Good to hear Bernd. I'll close to reflect that but please re-open if the issue
returns. Thanks for filing the bug.
