Bug Description
In the first two weeks of owning a Broadwell T550, I have suffered about two dozen abrupt power-offs. This has happened:
a) While resuming from suspend.
b) While in normal operation and just moving the mouse.
c) While switching from X to console by pressing ctrl-alt-F1.
There was no kernel panic, no log files, just an abrupt power-off.
In conjunction with several other HD5500 issues, I am starting to suspect the intel video driver, and have switched to the modesetting driver. Setting the Intel driver to use AccelMethod: none made the system more reliable but did not eliminate crashes.
Workaround: Put the following in /etc/X11/xorg.conf:
Section "Device"
Identifier "intel"
Driver "modesetting"
