Description bcling 2001-03-07 16:55:10 EST
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

Mar  7 09:28:10 localhost kernel: end_request: I/O error, dev 02:00
(floppy), sector 0

Comment 1 bcling 2001-03-07 16:57:16 EST
KDE doesn't have this problem.
Comment 2 Alexei Podtelezhnikov 2001-03-07 19:14:12 EST
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.
Comment 3 David Mason 2001-03-08 10:01:12 EST
owen - I can't reproduce... could it be a magic dev situation?
Comment 4 Owen Taylor 2001-03-08 11:32:10 EST
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.
Comment 5 bcling 2001-03-08 12:02:24 EST
It is magicdev... confirmed with killall magicdev.

Did not notice the behavior on 7.0.90... but it may have been an oversight.
Comment 6 bcling 2001-03-08 12:32:13 EST
The process is listed below:

magicdev --activate-goad-server GOAD:magicdev:19990913 --goad-fd 10
Comment 7 Owen Taylor 2001-03-08 12:33:57 EST
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?

Comment 10 bcling 2001-03-08 14:14:30 EST
7.0.90 had magicdev-0.2.7-5, same as 7.0... so there were obviously no problems
Regressing to the previous version from current version of 0.3.0-4 corrects this
Comment 11 Owen Taylor 2001-03-08 14:37:43 EST
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,
Comment 12 Preston Brown 2001-03-08 15:41:54 EST
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.
Comment 13 Owen Taylor 2001-03-08 16:05:36 EST
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.)
