Comment 34 for bug 384579

@dougfractal -- thanks for those logs. Noticed something I had missed before now:

    [ 5.145495] Platform driver 'floppy' needs updating - please use dev_pm_ops
    [ 5.145530] Floppy drive(s): fd0 is 1.44M
    [ 5.165752] FDC 0 is a post-1991 82077
    [ 5.201942] EDAC MC: Ver: 2.1.0 Jul 14 2009

We actually appear to have loaded the driver and continued in a reasonable time frame. Some time later we then start to see the errors:

    [ 18.140540] end_request: I/O error, dev fd0, sector 0
    [ 30.304489] end_request: I/O error, dev fd0, sector 0
    [ 30.304493] Buffer I/O error on device fd0, logical block 0
    [ 42.472405] end_request: I/O error, dev fd0, sector 0
    [ 42.472408] Buffer I/O error on device fd0, logical block 0
    [ 54.632477] end_request: I/O error, dev fd0, sector 0
    [ 54.632480] Buffer I/O error on device fd0, logical block 0

This could be related to udev probing of the device. Could you attach the /var/logs/udev file from a boot showing the issue, and also could you report the output of the command below:

    sudo time /lib/udev/devkit-disks-part-id /dev/sda

Thanks.
