The polling method is also noisy, causing kernel messages to be written to text consoles: .... [355682.176027] end_request: I/O error, dev fd0, sector 0 [355684.176029] end_request: I/O error, dev fd0, sector 0 [355686.176036] end_request: I/O error, dev fd0, sector 0 [355688.176026] end_request: I/O error, dev fd0, sector 0 .... ACK, this badly needs fixing. I haven't gotten to this because Fedora doesn't automatically load floppy.ko (yeah, bad excuse). I'm going to be in the office on Wednesday so I'll fix it then (I don't have a box with a floppy drive at home). In Ubuntu we don't force floppy.ko either, it just seems to get autoloaded with the normal udev/modalias mechanism. Unfortunately I can't personally help with debugging here, it's been ages since I had my last floppy drive, but I'm happy to relay testing questions to the reporter, or create some test packages for him. https://bugs.launchpad.net/bugs/384579 has some udev log and devkit-disks --dump on a computer where a floppy is detected, so that might help. By the way, you’d expect it would be possible to do a noiseless poll with the floppy drive. AmigaOS did the clicky poll periodically, and someone created a utility that made it silent. It worked perfectly. http://aminet.net/disk/misc/anticlick.readme Fixed on master: http://cgit.freedesktop.org/DeviceKit/DeviceKit-disks/commit/?id=b95485015a9fe8ec2c38bf305029410d5ddab062 (In reply to comment #4) > By the way, you’d expect it would be possible to do a noiseless poll with the > floppy drive. > > AmigaOS did the clicky poll periodically, and someone created a utility that > made it silent.

Actually, it almost worked in Windows 95 but not quite so - see http://blogs.msdn.com/oldnewthing/archive/2009/04/02/9528175.aspx for a good write up. |
