I applied the patch on Kernel 4.8.0-rc8-00771-g8ab293e: result is a stable system as before, so at least it didn't introduce a regression. Then I disabled the override for my card below: diff --git a/drivers/gpu/drm/radeon/si_dpm.c b/drivers/gpu/drm/radeon/si_dpm.c index e6abc09..bcaa675 100644 --- a/drivers/gpu/drm/radeon/si_dpm.c +++ b/drivers/gpu/drm/radeon/si_dpm.c @@ -2924,7 +2924,6 @@ struct si_dpm_quirk { /* cards with dpm stability problems */ static struct si_dpm_quirk si_dpm_quirk_list[] = { /* PITCAIRN - https://bugs.freedesktop.org/show_bug.cgi?id=76490 */ - { PCI_VENDOR_ID_ATI, 0x6810, 0x1462, 0x3036, 0, 120000 }, { PCI_VENDOR_ID_ATI, 0x6811, 0x174b, 0xe271, 0, 120000 }, { PCI_VENDOR_ID_ATI, 0x6811, 0x174b, 0x2015, 0, 120000 }, { PCI_VENDOR_ID_ATI, 0x6810, 0x174b, 0xe271, 85000, 90000 }, Result is the same as without your patch: black screen and non responsive system. Should I also revert "drm/radeon: load different smc firmware on some SI variants"?
