Hi all,

It looks like some misconfiguration in /etc/ntp.conf cause kernel to panic when switching to runlevel 0 :

Code:
user@localhost ~ $ cat /etc/ntp.conf
server 0.gentoo.pool.ntp.org
server 1.gentoo.pool.ntp.org
server 2.gentoo.pool.ntp.org
server 3.gentoo.pool.ntp.org

server 127.127.1.0
fudge  127.127.1.0 stratum 10

# Default configuration:
# - Allow only time queries, at a limited rate, sending KoD when in excess.
restrict default nomodify nopeer noquery limited kod
restrict 127.0.0.1

#disable monitor

This is not a panic. This is a BUG, which is at least sometimes recoverable. If it were a panic, you would not get any log files written with the error text.

The error happened for rmdir, not ntpd, and happened one second before ntpd terminated. I see you are using proprietary and out-of-tree modules. Is the problem reproducible on an untainted kernel? Can you narrow down exactly what service change triggers this?

Nvidia proprietary drivers are blacklisted from now on, will try to reproduce so tune in to find out which service causes It.

Be interesting to know what filesystem is in use.

Looks like issue was triggered by a popup window with faulty nvidia drivers :twisted:

Hi,

Issue has desappearded, however nouveau kernel logs drivers section shows that "module with unavailable key is rejected" twice. Kernel is secure booted, kernel modules are signed.

Is there a way to find on which modules that are ?
