Title:
Can't login after boot with Kernel 4.11.0-rc7, soft lockup in systemd-
logind
Status in linux package in Ubuntu:
Incomplete
Bug description:
Used distribution:
Ubuntu Gnome 16.04 with Kernel 4.11.0-rc7
After logging in to the gnome login screen, the system freezes. Trying to
login using the shell (Ctr+Alt+F1) also freezes the system. The following
ouptut appears on the shell repeatedly:
NMI watchdog: BUG: soft lockup - CPU#0 stuck for 22s! [systemd-logind:913]
Steps to reproduce the problem:
Boot Ubuntu Gnome 16.04 with Kernel 4.11.0-rc7 and try to login after boot.
Further testing results:
Using Mainline Kernel Version 4.11.0-rc6, login works fine
Using Kernel Version 4.10.11, login works fine
Using Kernel Version 4.10.12, the issue is present
==> It might be possible the issue has been introduced in a commit in
4.11.0-rc7 and has been backported to 4.10.12.
