--- Comment #14 from Jens <jens-bugs.freedesktop.org at spamfreemail.de> ---
Summary:

1)
I could not reproduce the above corruption error with "nomodeset" and only
using the console (no X) after about 10 suspend/resume cycles during a parallel
make -j4.

2)
Upon restarting lightdm and logging in, this is printed to the console when
using "nomodeset":
[+21.57s] WARNING: Error activating login1 session:
GDBus.Error:org.freedesktop.DBus.Error.Failed: Operation not supported

I do not get this when not using this boot parameter.

Full boot command line: BOOT_IMAGE=/vmlinuz-3.18.0-rc1+
root=/dev/mapper/ubuntu--vg-root ro quiet splash no_console_suspend=1
netconsole=6666 at 192.168.178.59/eth0,6666 at 192.168.178.62/ crashkernel=384M-:128M
vt.handoff=7

3)
After console freezes, there is nothing strange in the logs (at least no
backtrace, oops or anything obvious.)
