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  |

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 ?
