Shutdown does not halt on my Dell Precision 390
the shutdown sequence prints on the console:
mount: / is busy
/etc/init.d/sendsigs does not terminate systemd-udevd
Only solution: enable and use ALT-SYSREQ REISUB (to keep the root fs clean)
I tried to change GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub (+ update-grub):
GRUB_CMDLINE_LINUX_DEFAULT="quiet nosplash reboot=pci" or
GRUB_CMDLINE_LINUX_DEFAULT="quiet nosplash reboot=bios" or
GRUB_CMDLINE_LINUX_DEFAULT="quiet nosplash acpi=force
Shutdown still hangs with 'mount: / is busy'
I even updated the BIOS from 2.0.4 to 2.06, no luck.
When booting from a Knoppix 6.0.1 CD with a 2.6 kernel, shutdown works and halts the system to poweroff state.
Any ideas?
Thanks
