problems with Mandrake 10.0 + kernel 2.6.8-rc2
Hi,
I've recently moved to Mandrake 10.0 (prompted by a defunct hard disk which neccesitated a complete re-install) and have had several problems. As a result I have upgraded my kernel from 2.6.3 to 2.6.7 and then 2.6.8-rc2. Unfortunately the fire may be hotter than the frying-pan (Old English Proverb) and I'm now in a state where I can't mount CDroms. I can read the raw device OK, so the basic driver (ide-cd) is OK, or at least it seems to be. I've added traces to isofs.ko and established that this initialises OK, but when I attempt to mount the driver it gets a return code of -EINVAL when it tries to read the superblock (get_sb_bdev?()).
I'm pretty sure that this must be something set up wrong somewhere as it's unlikely that 2.6.7 (or 2.6.8) would be released without someone somewhere needing to mount a cdrom, but I have no idea where to go from here. I am not a kernel-hacker, though I did some many moons ago, but I know enough to patch and rebuild modules and test them. I took a look at the source code of ide-cd.c but can't make much sense of the way things are done these days, and have too many other things to do....
Can anyone give me advice (or even better a fix)?
I'd appreciate being CC'd on any response as I'm not on the kernel mailing list (too many others to wade through).
Many thanks,
Bill

First step in bug reporting is including a step-by-step way to reproduce (ie what you do when it fails). Also please include a dmesg -s100000 from a booted system, and your .config from 2.6.7.

Mathieu,

odd....
can you try removing the umask=0 option ?
does 'mount -t iso9660 -o ro/dev/hdc/mnt/cdrom' fail too ?
Interesting - that's fixed it. I would not have believed that that could cause my problems. Why on earth would Mandrake put it in if it does that!?
Thanks for the advice,
much appreciated,
Bill
