Public bug reported:
Binary package hint: linux-image
I upgraded my ThinkPad X32 notebook to Lucid beta. The notebook does not
have floppy drive, but the floppy kernel module causes very high cpu
iowait usage for about 20 minutes after initial booting, while issuing
the following error messages:
[ 1123.553851] Buffer I/O error on device fd0, logical block 0
[ 1136.618649] end_request: I/O error, dev fd0, sector 0
Manually removing(rmmod) and loading(modprobe) the floppy module later
cannot reproduce the high cpu iowait usage.
High iowait usage is gone after blacklisting the floppy module.
