Bug Description

Binary package hint: linux-image-2.6.20-6-generic

After a few minutes of use USB external mouse and keyboard stop working. Unplugging and plugging again doesn't work. "sudo /sbin/rmmod usbhid" freezes so that even kill -9 doesn't help. Rebooting is the only way to get back to normal. This is on a Toshiba Satellite L25-S1192 laptop. Using the latest Feisty with fglrx and madwifi drivers.

Thanks for taking the time to report this bug. Unfortunately we can't fix it, because your description didn't include enough information.

Please include the following additional information, if you have not already done so (please pay attention to lspci's additional options), as required by the Ubuntu Kernel Team:
1. Please include the output of the command "uname -a" in your next response. It should be one, long line of text which includes the exact kernel version you're running, as well as the CPU architecture.
2. Please run the command "dmesg > dmesg.log" and attach the resulting file "dmesg.log" to this bug report.
3. Please run the command "lspci -vvnn > lspci-vvnn.log" and attach the resulting file "lspci-vvnn.log" to this bug report.

For your reference, the full description of procedures for kernel-related bug reports is available here: <http://wiki.ubuntu.com/DebuggingKernelProblems> Thanks!

Try the Feisty Beta 1 kernel. Your issues are ACPI related. If they persist, then try booting without ACPI, e.g., 'acpi=off'.

It doesn't happen with 2.6.20 kernel from Fedora Core 6

Upgrading to 2.6.22-1-generic kernel from gutsy repository fixed my problem. All my USB devices work reliably now. Should I close this bug which was filed against 2.6.20 kernel?

No, please don't close the bug as the issue still exists with the 2.6.20 kernel. There may be a stable release update of the kernel coming and we will want to see if it resolves this issue.
