Bug Description

Without any apparent reason, my CPU load is 100% and the kernel log contains lots and lots of these:

 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!

I haven't seen that bug again after I reported it, so I don't know if it still exists. But here's the info you requested anyway:

uname -a:
Linux kaffeetisch 2.6.17-11-386 #2 Thu Feb 1 19:50:13 UTC 2007 i686 GNU/Linux

Looks like lspci needs superuser privileges to access some information.
