Description of problem:
System dies, when user try unmount floppy. Floppy (FAT) mounts OK. Then we reads 
data from floppy - OK too. Write something to floppy - OK, but when "umount 
/mnt/floppy" after writing - system down. No erros, no warnings, mouse point 
disappears, keyboard off, system hangs off.
Using mmount a:, mcopy, - identical results. mcopy faults after writing. cp may 
fault after autofsd try umount(?) floppy. KDE - when user umount floppy by menu.
This bug appears after installing video drivers for nVidia GForce4MX (drivers by 
NVidia "nvidia", not RH9 common video drivers "nv"). 
Some manipulations with /etc/fstab got us strange results: sometime (in very few 
cases) this bug do not appears, but why, it's undefined, because after rebooting 
error appears again.

Steps to Reproduce:
1.Install nVidia drivers: #sh NVIDIA-.x.something.x.y.z..;
  I have got drivers from official page of nVidia.
   $mount -t vfat /mnt/floppy /dev/fd0
   $cp /etc/fstab /mnt/floppy
   $umount /mnt/floppy
   ....System crash.
  or try
   $mcopy /etc/fstab a:
   ....System crash.

My videocard: GForce4MX400.

Some news about 99299: At nVidia forum I found one topic about lockups of nVidia 
driver under XFree86. It's recommended to update XF86 to version
At XF86 site I have read info about this last patch and found some aviable 
causes of failure. Do I need update XFree?
But one important thing : I have see this problem WITHOUT XF, at run-level 3, 
too. And how X-server depends of file system?

The nVidia drivers are unsupported for a reason.
