--- Comment #2 from EoD EoD@xmw.de --- (In reply to Alex Deucher from comment #1)
Does it work any better with the latest code in: http://cgit.freedesktop.org/~agd5f/linux/log/?h=drm-next-4.5-wip
Yes, there are improvements:
When I go into standby in a virtual terminal it can recover, but still writing the following error to dmesg:
kernel: PM: resume of devices complete after 6591.636 msecs kernel: Restarting tasks ... done. kernel: amdgpu 0000:01:00.0: GPU fault detected: 147 0x0f080008 kernel: amdgpu 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x001001E1 kernel: amdgpu 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x02000008 kernel: VM fault (0x08, vmid 1) at page 1049057, read from 'TC2' (0x54433200) (0)
When I switch back to X11 the system locks up, but unlike before I still can execute SysRq.
This is a major improvement to the drm-next-4.5 branch!
