            Bug ID: 99316
           Summary: Radeon crash when laptop on AC power
           Product: DRI
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: major
          Priority: medium
         Component: DRM/Radeon

AC Power Unigine Heaven dmesg

I have a Dell laptop with an Intel iGPU and a Radeon dGPU (a Firepro W5130M,
recognized as a Radeon HD 8830M by lspci).

Whenever I attempt to use the Radeon card via DRI_PRIME=1 while the laptop is
plugged in, the card crashes. When on battery the card performs fine.

One way I have tested this is with glxgears. Often glxgears will work the first
time it is run, but if it is closed and then opened a few seconds later, it
will crash.

I have also tried running programs like Portal 2 and Unigine Heaven. These
always hang. Unfortunately the error messages produced in dmesg are not the
most consistent. Sometimes I get a backtrace, sometimes even a kernel panic on
reboot.

I'll post the various logs I have. One thing I have found is that glxgears does
not crash if I use radeon.runpm=0, however it still hangs when running
something like Portal.

AC Power glxgears

The last part of the log, 121 onward is the second failed attempt for glxgears.
The previous part 94-96 is a successful glxgears attempt seconds earlier. These
logs are the only thing that have been consistent from my tests.

Possibly a duplicate of bug 98897.  Does attachment 128780 fix the issue?

kernel panic

I get these sometimes when I reboot after testing the card. Usually after
testing it with something like Portal or Unigine Heaven. It doesn't always
happen.

Sorry it's a picture, I haven't been able to get kdump to work, though if
necessary I'll give it another try.

It's been a while, but this is still happening. I've moved distro by now
(Fedora 26) but I'm getting the exact same error. Though it's nearly identical,
I'll upload a new log generated by journalctl -b --no-pager | egrep
'radeon|drm|kernel' >> radeon_crash

To clarify, since it has been a while, the radeon card crashes when the laptop
is plugged in, but not when it's unplugged. It has been like this as long as I
have had it (since July 2016)

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.

Is the GPU at low power while plugged in, or always?

glmark2 while plugged in instantly crashes for me, but on battery I get a score
of 1395 which is horrible compared to the 3680 from my integrated card. Plus
horrible rendering artifacts. But I'm not sure if that is really related to my
main problem.

This is "/sys/kernel/debug/dri/0/radeon_pm_info" on battery with glmark2 for
me:

uvd    vclk: 0 dclk: 0
power level 2    sclk: 40000 mclk: 30000 vddc: 900 vddci: 0 pcie gen: 3

Oddly enough, a completely different format than yours.

This card seems to have a multitude of problems

Rendering artifacts on battery

Perhaps not entirely related, but these are rendering artifacts while on
battery with glmark2. Note the horizontal lines, this is the main issue, that
and major stuttering. glxgears produces similar results.

Hi!
As an owner of the same GPU, I can confirm this bug still appears under linux
4.15.0-rc7.
The card card crashes or hangs when used with DRI_PRIME=1. After seeing this
report, I tried with the laptop plugged out and it surprisingly did work.

It would be nice to have a solution as the w5130m isn't currently supported by
amdgpu either leaving it unusable under linux.

Glad to finally find someone else with the same issue! I was beginning to think
I was the only one.
