Description Michal Jaegermann 2001-06-11 19:57:49 EDT
Description of Problem:
Here is what I see on my screen when trying to mount a CD (no,
no 'magicdev' abomination in sight):

toaster:/dev# mount /cdrom/
hdd: tray open
end_request: I/O error, dev 16:40 (hdd), sector 112
ISOFS: unable to read i-node block
hdd: tray open

Another CD, which reads fine on another machine:

end_request: I/O error, dev 16:40 (hdd), sector 236
ISOFS: unable to read i-node block
toaster:/dev# eject
VFS: busy inodes on changed media.

(and CD ejects after that complaint)

How Reproducible:
So far with 100% guarantee if I try to use a kernel from Red Hat.
Oh, yes, 'mount /cdrom' is a valid command in my configuration.

Additional Information:
The first CD happens to be one used to perform an upgrade so it seems
to be readable. :-)

All these problems automagically vanish the moment I will boot a kernel
not from a distribution but what I compiled myself (2.4.5-ac8 or one
of 2.2 kernels). 'eject' also works without any problems.

/var/log/messages do not contain any extra information above what
is already shown.

Michael, I'm assuming that this works ok for you now in the actual 7.1 release?
I've not seen anyone else report a similar problem so I'm assumiong that it'll
be safe to close this

Comment 2 Michal Jaegermann 2001-08-30 19:20:21 EDT
Yes, indeed.  I did not see the trouble with recent software versions
(but I did not investigate what was the real reason behind this;  I hope
that you have some idea :-).
