            Bug ID: 108031
           Summary: [Regression] amdgpu_device_ip_init failed on Bonaire
                    XT
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium

4.19 rc4 boot log (black screen)

AMDGPU fails to initialise the graphics card with mainline kernel 4.19, from
rc1 to rc4, resulting in a black screen on boot.

4.18.8 boots to the desktop without any fatal errors, and functions as
expected.
The regression happened some time before 4.19 rc1 but after the 4.18 release.

Graphics card is:
01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc.
[AMD/ATI] Bonaire XT [Radeon HD 7790/8770 / R7 360 / R9 260/360 OEM]
[1002:665c]

I attempted to bisect it, but I kept hitting another (possibly unrelated) bug
that would cause a panic on boot and thus was unable to.
Attached are the kernel logs from both 4.18.8 and 4.19 rc4.

Running the latest available firmware for this card from the git repo.

4.19.0 Debian kernal boot log (external screen working)

I can reproduce this with

    00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
Carrizo (rev c4)
    03:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Bonaire
XT [Radeon R9 M280X] (rev 80)

on a “Lenovo ideapad Y700-ACZ”.

When I boot into the released Linux 4.19.0 from Debian I get a blank screen,
however today I discovered that if you have an external displayed plugged
during boot-up that display will be successfully enabled and you can then log
in as usual. The internal laptop display will not ever be enabled however and
checking under *Systemsettings* → *Monitor Settings* (KDE) will not show it
either. Also the entire system will feel very sluggish (not CPU or disk
related, I checked) and is only usable with lots of patience. On shutdown the
system will then hang (nothing about this in system logs unfortunately).

Remove amdgpu.dpm=1 from your kernel command line.  The default dpm
implementation changed in 4.19.

and setting dpm=1 overrides that resulting in different behavior.  power
management is always enabled by default.  the dpm option is only for debugging
and switching between implementations for asics that contain multiple
implementations.

Using the latest Debian kernel (4.19.0-2, which apparently corresponds to Linux
version 4.19.16, with 4.19.0-1 having corresponded to 4.19.13) this issue does
not affect me anymore.

I looked through the kernel commits between the versions but none looked very
related, there was some stuff about DP MST which maybe somehow relevant since
the display is connected using eDP. Dunno.

Anyways, works for me now.
