Bug ID: 111980 Summary: Rebbot and shutdown doesn't work on specific hardware Product: DRI Version: XOrg git Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: not set Priority: not set Component: DRM/Radeon Assignee: dri-devel@lists.freedesktop.org Reporter: lei.pero@gmail.com

When system shutdown/reboot is initiated, everything works as it should, journal doesn't show any error and it reaches target reboot (for example), display shuts down properly, but PC stays powered on (requiring hard reset) indefinitely.

This happened after kernel upgrade, after bisectiing, commit that was to blame was bellow, after removing just that specific commit, it would work as expected:

894c414129a8d9ef1b2de443015e4dde6085f64f is the first bad commit commit 894c414129a8d9ef1b2de443015e4dde6085f64f Author: KyleMahlkuch kmahlkuc@linux.vnet.ibm.com Date: Wed Jul 31 17:10:14 2019 -0500

drm/radeon: Fix EEH during kexec

[ Upstream commit 6f7fe9a93e6c09bf988c5059403f5f88e17e21e6 ]

During kexec some adapters hit an EEH since they are not properly shut down in the radeon_pci_shutdown() function. Adding radeon_suspend_kms() fixes this issue.
