[amdgpu] ASSERT()'s in write_i2c*retimer_setting() functions
Hello, I've built recently a new box with a Ryzen3 2200G APU. Each time I plug in an HDMI cable ( to a TV or Monitor ), or boot with HDMI connected a lot ASSERT()'s from write_i2c*retimer_setting() functions are triggered. I see the same on a Laptop with a Ryzen7 3750H with hybrid GPU configuration. Besides the noise in dmesg and the delay on boot, everything is working fine. I cannot find anything wrong or broken. Since the write errors seem to not be fatal, I think a friendly message would help more instead of flooding the dmesg with dumps while everything is working properly. Why is ASSERT() used there? I have a dmesg from the Ryzen3 box with drm.debug and a snipped from the Laptop ( not near me right now ) uploaded there: https://crazy.dev.frugalware.org/amdgpu/ Please let me know if you need more information, If needed I can upload a dmesg from the Laptop with drm.debug too. Best Regards, Gabriel C

[Regression] 5.3-rc8 suspending from X broken with amdgpu
Hello, I am testing latest rc8/Linus git tree on my new Acer Nitro 5 (AN515-43-R8BF) Laptop. The box has an Ryzen7 3750H APU+RX 560x hybrid GPU(s). Suspending ( closing the Lid ) from tty without X up is working fine, however with X running doing the same does not work. The display remains black. It seems to be triggered from .. dcn10_hw_sequencer.c:932 dcn10_verify_allow_pstate_change_high.cold+0xc/0x229 [amdgpu] The dmesg is way to big to post there so I uploaded it: dmesg: http://crazy.dev.frugalware.org/Nitro5/dmesg.one.txt lspci: http://crazy.dev.frugalware.org/Nitro5/lspci.nnvv.txt http://crazy.dev.frugalware.org/Nitro5/lspci.txt config: http://crazy.dev.frugalware.org/Nitro5/config.nitro5-5.3-r8git I didn't tested any other rcX kernels so I cannot tell if all are affected, but 5.2.x kernels are working fine on this box. The dirty state of the build is because this patch, which fixes the NVME device on that box: https://lkml.org/lkml/2019/9/11/569 If you need more infos please let me know. Also I can test any kind patches. Best Regards, Gabriel C
