RE: Mount locks on bad ISO image?

[Aaron Lunansky]

I'm running 2.4.2 so it's probably just the broken loop device.


Thanks,
Aaron

Answer 1: in 2.4.2 the loop device does not work
 (but things are better in the -ac patches).
Answer 2: the kernel tends to believe filesystem data,
 and a corrupted filesystem can seriously confuse the kernel.

If you make sure that the problem does not lie in loop
(you can mount other images without problems), then
I wouldnt mind seeing your image (or rather, the first
MB or two of it) to see whether the isofs code must be
improved. (In that case, put some smallish fragment up for ftp
and mail the URL to aeb@cwi.nl. Don't mail cd images.)

Mount locks on bad ISO image?

[Aaron Lunansky]

I tried mounting a file as an ISO image (turns out it was corrupted) - after
running mount file.iso /cdrom -o loop
mount hung and did not respond.. I could not ^Z it into the background, or
kill, or kill -9 it...

I'm certain that I have ISO and loopback support compiled into my kernel.

Anyone know what might be going on?
