After a non-deterministic amount of time the system may hang with a message like this in the logs: "[amdgpu 0000:67:00.0: [drm] *ERROR* [CONNECTOR:78:eDP-1] commit wait timed out]" Affects users of laptops that contain: * AMD Rembrandt (Yellow Carp) or AMD Phoenix (Pink Sardine) chips * eDP panels with Parade TCONs (8-03 and 8-01 both reported to fail) [ Test Plan ] * Test an affected laptop with the newer firmware and ensure that PSR-SU function can be enabled and system is stable. * Ensure other functions such as hotplugging monitors and suspending continue to work. [ Where problems could occur ] * Affected firmware only is loaded on Rembrandt and Phoenix laptops. Problems would be localized to these machines. [ Other Info ] The minimum firmware needed to help these hangs: * Rembrandt: 0x400003a or later * Phoenix: 0x8001000 or later The following commit upgrades the firmware for Rembrandt (amdgpu/yellow_carp_dmcub.bin) to 0x400003c: 9dbd8ec2 ("amdgpu: DMCUB updates for various AMDGPU asics") The following commit upgrades the firmware for Phoenix (amdgpu/dcn_3_1_4_dmcub.bin) to 0x8001a00: 045b2136 ("amdgpu: update DMCUB to v0.0.172.0 for various AMDGPU ASICs") The TCON in a given laptop can be identified from the DPCD with this script: https://gitlab.freedesktop.org/drm/amd/-/blob/master/scripts/psr.py To manage notifications about this bug go to: https://bugs.launchpad.net/linux-firmware/+bug/2024774/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
