I hope this PR is still "hot", otherwise I need to open a new one.
On a Lenovo T560 running 13-STBALE, the HD520 graphics isn't working any more.
Techniscal specifications see below.
Background:
Customized Kernel (but also crashes with GENERIC). Port graphics/drm-510-kmod
is rebuilt every time the kernel is rebuild, if the module(s) is (are)
downloaded via pkg from the official FreeBSD package repository, one will
receive an error message on loading the module into the kernel like:
[...]

The kernel has been compiled with debugging facilities ON as defaulted in
GENERIC.
Phenomenon:
Starting FreeBSD and loading the drm-kmod module i915.ko works fine. I also get
to the point with the presentation of the xdm login. Starting windowmaker
(x11-wm/windowmaker), the Labtop immediately goes blank/dark and reboots. There
is no trace of a core dump or a debugger console as expected.
Changing the windowmanager from wmaker to, say, blackbox (x11-wm/blackbox) or
twm (x11-wm/twm, mitigates the problem, does mean: the OS starts the GUI. But
in case of twm, opening xterm results in the very same crash behaviour as with
wmaker. Running blackbox gives some relaxed behaviour, but starting any(!)
larger X11 application, like LibreOffice (soffice), Firefox or Thundebird. But
even with clients with an obvious smaller memory foortprint it takes a while
until a crash occurs.
This behaviour is seen on a couple of T560s around here with 13.2-RELENG (not
well tested, just a quick check), 13-STABLE as shown below.
I have no exact point in time when the problems occur, bu it was the transition
between 13-STABLE -> 13.2-STABLE before the official RELEASE of 13.2 (running
the 13-STABLE by compiling the whole sources on a regular basis).
While keeping the kernel and the way it is compiled an invariant, I changed
from seld-made poudriere built ports (with recent 13-STABLE jail) to official
FreeBSD package repository and back - with no effect on the result of a crash.
As reported, I can not provide with a coredump or anything sent by the kernel
debugger since there is none of such a postmoretm info.
The T560 is running the latest firmware/BIOS available from Lenovo (V1.45)
