Hi,

I have updated my box today and after rebuild nvidia I rebooted.
After rebbot I got an issue:

umount: /sys : device is busy
mount: none already mounted or /sys busy

The update included "util-linux-ng", is there a known problem ?

my mtab
/dev/sda6 / ext4 rw,noatime 0 0
/dev/sda1 /boot ext2 rw 0 0
/dev/sda7 /home ext4 rw,noatime 0 0
/dev/sda3 /save ext4 rw,noatime 0 0
devpts /dev/pts devpts rw 0 0
none /proc proc rw 0 0
usb /proc/bus/usb usbfs rw 0 0
/tmp /tmp tmpfs rw,noatime,mode=1777 0 0

Yes, /sys is not mounted and I'm pretty clueless.

Would appreciate any help.

I have the same problem since I have updated udev from version 156 to
version 159. I think the problem is udev related since it disappears
when I downgrade to udev 156 again.

Unfortunatly I have not found a solution which lets me use udev 159 and
mount the sysfs filesystem. I have tried changing the /etc/rc script
and /etc/fstab config file, but I did not reach a point where it worked
again. So I temporarly downgraded to udev 156 again to keep my system
usable.

I will search for a solution.

Yes, /sys is not mounted and I'm pretty clueless.


Inserting the command

/bin/mount -o remount /sys

in /etc/rc (right after the line "/bin/mount -a -O no_netdev") works for
me. The system appears to function normally after that.

Bernd
