Console mode resume glitch, journal extract (nightly kernel)
I tried suspend/resume with X disabled (console mode) with the Intel DRM
nightly kernel (same as before) just in case, and there is a i915/DRM glitch.
The system recovers and works fine, but there's a console output and journal
info. It occurred 3 times out of 3, so may be systematic (more tests to do). I
attached the relevant journal extracts.
If it's systematic, it may not fully explain the lock-up when X is enabled (as
the lock-up is not systematic), but hopefully may be related and could give an
idea where to look. TBC.
In any case, when X is enabled and the system locks-up it's a hard lock-up: the
network is down (no reply to ping), and USB is also down (when hooking an
optical mouse, its bottom LED doesn't light up). So not easy to see what
happened...
For more info on the laptop environment, see Debian initial bug:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=794393
Let me know if there's anything I can do to collect useful information.
I'll try in console mode with the older kernels I used too to see if I get a
similar behavior.
