Comment # 4 on bug 1177018 from Philippe Cond���

Hello,

I'm on tumbleweed  and my system is  updated on each snapshot via "zypper dup"

I see the same problem from time to time: sometimes it occurs when  I try to
unlock the sytem , sometimes when I scroll in firefox for a page still in load.

I found this error 
"Nov 19 08:36:57 hpprol2 systemd[1]: systemd-udevd.service: Watchdog timeout
(limit 3min)!
Nov 19 08:36:57 hpprol2 systemd[1]: systemd-udevd.service: Killing process 618
(systemd-udevd) with signal SIGABRT."

This is followed by these watchdog error repeated more > 25 times.

...."

The system is then locked (numlock doesn't respond and changing to VT is not
possible) --> I need to do a hard restart.
