[Bug 1580697] Re: Kernel freezes after drm_wait_one_vblank timed out
apport information
** Tags added: apport-collected
** Description changed:
Using kernel 4.4.0 from Ubuntu GNOME 16.04 I get a lot of warnings
'drm_wait_one_vblank timed out' while booting and every time when I
switch user or session via Alt-Fn. Example logs will be attached, I used
this for saving the log:
journalctl -b --system --no-pager |tee bootlog-$(uname -r)-$(lsb_release
-sr)
I suspect this may be related to some of my problems (slow switch,
freeze, wrong VT: Alt-Fn6 roots to tty3) when switching virtual
terminal.
- I see these messages on 16.04 or 14.04 when using kernel
- 4.4.0-21-generic, 4.4.0-22-generic or mainline kernel
- 4.4.0-040400-generic or 4.5.2-040502-generic, but mainline kernel
- 4.3.6-040306-generic does not throw this message and there are no
- problems with 4.3.6 while switching VT.
