[Bug 99316] Radeon crash when laptop on AC power

https://bugs.freedesktop.org/show_bug.cgi?id=99316

--- Comment #10 from mat42x@yahoo.de --- I have also a Dell notebook with the same dGPU, but cannot reproduce your error with Ubuntu 16.04 kernel 4.10.0.

Instead I have the problem, that the dGPU only gets powered at a low frequency, and becomes slower than the Intel GPU by doing so.

When I run glmark2, I look at "/sys/kernel/debug/dri/0/radeon_pm_info" and always see the following output:

default engine clock: 925000 kHz current engine clock: 299990 kHz default memory clock: 1000000 kHz current memory clock: 148990 kHz voltage: 1225 mV PCIE lanes: 16

Btw.: This dGPU cannot be connected to a CRT directly, as there seems to be no connection available at all.
