Red Hat Bugzilla – Bug 99299
System failure when floppy with new datas umount
Last modified: 2007-04-18 12:55:43 EDT
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
$mcopy /etc/fstab a:
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 18.104.22.168.
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.
