** Description changed: Binary package hint: linux-image I upgraded my ThinkPad X32 notebook to Lucid beta last weekend. The notebook does not have a floppy drive, but the floppy kernel module causes very high cpu iowait usage for about 20 minutes after reboot. At the same time, it keeps issuing error messages as follows: [ 1123.553851] Buffer I/O error on device fd0, logical block 0 [ 1136.618649] end_request: I/O error, dev fd0, sector 0 - Reproducible in 2.6.32-16-generic and 2.6.32-17-generic. + Reproducible in 2.6.32-16-generic, 2.6.32-17-generic, 2.6.32-22-generic + and the upstream kernel 2.6.34rc7. Manually removing(rmmod) and loading(modprobe) the floppy module later cannot reproduce the problem. - One workaround is to blacklist the floppy kernel module. + Work-arounds: + 1. blacklist the floppy kernel module. + 2. disable Legacy Floppy Drive in ThinkPad BIOS. - - --- + --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.21.
