I have a laptop with "AMD A9-9420e RADEON R5, 5 COMPUTE CORES 2C+3G"
Without the amdgpu module it always hibernates.
With just the amdgou module (without amdkfd and amd_iommu_v2) it reboots instead.
With all 3 loaded it hangs at "PM: Syncing filesystems ... "
All I get in the logs is -
May 19 08:32:53 diamond systemd: Reached target Sleep.
May 19 08:32:53 diamond systemd: Starting Hibernate...
May 19 08:32:53 diamond systemd-sleep: Suspending system...
May 19 08:32:53 diamond kernel: PM: hibernation entry
May 19 08:32:53 diamond kernel: PM: Syncing filesystems ...
-- Reboot --
The device suspends just fine.
I currently use the following module options -
options amdgpu dc=0 si=0 cik=0 exp_hw_support=0 aspm=1 dpm=1 bapm=1 hw_i2c=1
radeon is not loaded (doesnt work on the card anyway)
Kernels tried -
arch lts 4.14.41
arch mainline 4.17rc5
and a couple of others
All showed the same symptoms and log entries.
