Public bug reported:
In Ubuntu Precise, the floppy disk drive's motor keeps running forever
as soon as the floppy is accessed (say, by doing a "mdir a:" or a
"fdformat /dev/fd0", or a "dd if=/dev/fd0 ..." ), and the floppy drive's
activity LED stays lit. Only when the disk is removed from the drive,
the drive stops. I'd expect the drive to stop spinning a few seconds
after the access is finished.
The accessing command returns normally and I can still access the drive
normally by giving another command afterwards. The problem is purely the
failure to deselect the drive and/or turn off the drive motor line.
This is a standard IRQ6/DMA2 floppy drive connected directly to the
motherboard's built in FDC with a standard 34-wire ribbon floppy cable.
The bug happens both with a normal 1.44MB drive and with a 1.2MB (5.25
inch) drive. The drives do not exhibit this problem in DOS or Windows
running on the same physical hardware, and I do not remember having this
problem in Oneiric either.
If you need more info on my system than the automatically generated
attachments provide, please ask.
