Bug ID: 100979 Summary: Radeon r4 on a6-6310(BEEMA) APU hard lockup on hibernate and on second resume from suspend Product: DRI Version: DRI git Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: major Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: soprwa@gmail.com
I'm using kernel 4.11 on gentoo with SI/CIK enabled on Lenovo G50-45 Notebook. Machine has AMD APU A6 6130 with Radeon r4 graphics card (Beema/Mullins). This CPU supports olny AMD IOMMU v1. There is no discrete graphic card on it, APU only.
When I try to hibernate this notebook it doesn't turning off. I have to press power button to reboot the machine. Similar situation is on "radeon" driver, and I had submitted bug report about this on kernel's bugzilla:
https://bugzilla.kernel.org/show_bug.cgi?id=191571
But in this situation I'm unable to bisect because as I remember correctly problem always occur on amdgpu driver, so I think those two can correlate with each other. (dmesg form hibernation process attached).
As for suspend. I can suspend/resume machine successfully only once in a row. Second time machine suspends correctly, but on resume I have hard lockup, fans are spinning on full rpm's and I cannot do anything but pressing power button to reboot(cold boot) the netbook. Moreover in dmesg after first suspend I've got error messages:
[drm:amdgpu_atombios_dp_link_train [amdgpu]] *ERROR* displayport link status failed [drm:amdgpu_atombios_dp_link_train [amdgpu]] *ERROR* clock recovery failed
Attachments: 1. Log after clean start. 2. Kernel's config file. 3. Log after hibernation process. 4. Log after first suspend/resume. 5. Log after second suspend/resume.
