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):
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.
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.
It would appear that the kernel system call is hanging.
USb storage has had a major rework since 2.4.2. Multiple hang bugs have been fixed.
