drm/radeon: Fix EEH during kexec (d02f5aab) · Commits · 戴 / test

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. Enabled only on PPC because this patch causes issues on some other boards. Signed-off-by:
