[plug] strange modprobe using up cpu?

[Chris Caston]

Hello,

I'm running Debian sid with kernel 2.6.3-1386 #2.

For some reason occasionally I notice my usually snappy UI slow to a
crawl. By the time I open and xterm and type in top I just manage to see
modprobe using up 80-90% cpu.

The following from kern.log *may* be related:

Jul  5 10:35:57 localhost kernel: mcd: initialisation failed - No mcd

Jul  5 10:36:16 localhost kernel: optcd: unknown drive detected;

Jul  5 10:36:33 localhost kernel: optcd: unknown drive detected;

Any ideas?

Thanks,
