root booting into Gnome continually accesses floppy drive (/dev/fd0)
Last modified: 2007-04-18 12:32:03 EDT
From Bugzilla Helper: User-Agent: Mozilla/4.76 [en] (X11; U; Linux 2.2.16-22-1121 i686) 7.0.91 custom install. As root, execute startx. Floppy drive light illuminates and stays on almost constantly. This does NOT happen as a non-root user. Error messages follow: (this error occurs multiple times, could not find any more descriptive error messages) Reproducible: Always Steps to Reproduce: 1. Install Red Hat Linux 7.0.91 2. Log on as root (either directly or su -) 3. startx 4. Normal users don't have this problem. Actual Results: Floppy light illuminates and drive access attempted. Expected Results: No light... ;-) No access, unless specified. Tested on three Intel systems (PII, PIII) with three different motherboards. Mar 7 09:28:10 localhost kernel: end_request: I/O error, dev 02:00 (floppy), sector 0 Mar 7 09:28:42 localhost last message repeated 16 times
KDE doesn't have this problem.
I can confirm. I saw this problem too. The only differences in my situation is that I didn't startx but rather have it restarted automatically after killing X. Not only did I see the light, but also heard the noises. This was on Athlon system on MSI's K7pro motherboard.
owen - I can't reproduce... could it be a magic dev situation?
It seems unlikely unlikely. Magicdev doesn't touch any drives unless the file system type is iso9660. But a quick way to check this would be to 'killall magicdev' and see if the drive light goes off.
It is magicdev... confirmed with killall magicdev. Did not notice the behavior on 7.0.90... but it may have been an oversight.
The process is listed below: magicdev --activate-goad-server GOAD:magicdev:19990913 --goad-fd 10
Strange, strange. Could you strace magicdev to see what it doing exactly. (That is, killall magicdev strace magicdev And provide the part that keeps on repeating at the end.) Could you also provide your fstab? Thanks, Owen

7.0.90 had magicdev-0.2.7-5, same as 7.0... so there were obviously no problems there. Regressing to the previous version from current version of 0.3.0-4 corrects this problem.
Though I can't think of what would have changed from 0.2.7 => 0.3.0 or 0.3.0 => 0.3.5 in this respect; and I can't see how from the code this could ever have occurred (unless someone recompiled it an enabled floppy support.... in the sources there is: /* #define FLOPPY_SUPPORT 1 */ /* This keeps the drive light on constantly */ could you grab the current 0.3.5 and see if the same problem occurs there? Thanks again, Owen
wolverine had cdroms and floppies listed as type "auto", and magicdev was supporting that. We have since reverted to iso9660 for cdroms and auto for floppies, and have magicdev only supporting type iso9660. Solved.
OK, glad to know this is resolved. (It can be hard to try and handle bug reports for a package hat you aren't on prospector for... I had no idea this change was made, and it also didn't get into the repository for magicdev which is on cvs.gnome.org.)
