Description of problem:
I tried to mount a /dev/sda1 (digital camera USB), and the process stop in
state D, after that i can't mount or unmount a thing and no one can kill
them, even in reboot i have to do a power reset.

Version-Release number of selected component (if applicable):


How reproducible:
Sometimes

Steps to Reproduce:
1. Add aline in fstab to mount like "/dev/sda1	/mnt/Fuji	vfat	 exec,dev,suid,rw,noauto,umask=0,users 0 0"
2. Then try to mount /mnt/Fuji
3. note: Fuji is a USB digital camera. It works sometimes.



Actual Results:  The /bin/mount process is freeze and no one can kill it,
even by a kill -9 or killall.
After that i can't mount or unmount anything.
A restar must be by power reset. It stop in "stopping automount"

Expected Results:  Mounted the digital camera.

Additional info:

I have a Athlon, 1Ghz, 256Mram, one IDE disc, a DVD ROM, kernel 2.4.2.
I'm affraid to lose information, doing the power reset.
Comment 1 Bernhard Rosenkraenzer 2001-09-09 20:32:27 UTC 
It would appear that the kernel system call is hanging.
Comment 2 Alan Cox 2003-06-07 17:15:47 UTC 
USb storage has had a major rework since 2.4.2. Multiple hang bugs have been fixed.
