After upgrading to Linux 4.19-rc3 (from 4.18.x), I can't switch to tty anymore, the monitor connected over DisplayPort goes into sleep mode. I see this in dmesg when it happens: [37342.777399] [drm:generic_reg_wait [amdgpu]] *ERROR* REG_WAIT timeout 10us * 3000 tries - dce110_stream_encoder_dp_blank line:922 [37342.777477] WARNING: CPU: 4 PID: 14403 at drivers/gpu/drm/amd/amdgpu/../display/dc/dc_helper.c:254 generic_reg_wait+0xe7/0x160 [amdgpu] [37342.777478] Modules linked in: uas usb_storage rfcomm ebtable_filter ebtables devlink ip6table_filter ip6_tables iptable_filter cmac bnep arc4 nls_ascii nls_cp437 vfat amdkfd fat snd_hda_codec_realtek snd_hda_codec_generic edac_mce_amd btusb btrtl amdgpu btbcm snd_hda_codec_hdmi btintel iwlmvm snd_usb_audio snd_hda_intel bluetooth kvm_amd snd_hda_codec snd_usbmidi_lib wmi_bmof mxm_wmi mac80211 snd_hda_core kvm uvcvideo videobuf2_vmalloc snd_hwdep videobuf2_memops snd_rawmidi jitterentropy_rng videobuf2_v4l2 videobuf2_common snd_seq_device chash iwlwifi irqbypass gpu_sched videodev snd_pcm crct10dif_pclmul ttm crc32_pclmul media drbg snd_timer evdev drm_kms_helper cfg80211 ansi_cprng ghash_clmulni_intel efi_pstore pcspkr drm snd k10temp ecdh_generic soundcore efivars rfkill crc16 sp5100_tco sg ccp [37342.777514] rng_core wmi pcc_cpufreq button acpi_cpufreq nct6775 hwmon_vid parport_pc ppdev lp parport efivarfs ip_tables x_tables autofs4 xfs btrfs xor zstd_decompress zstd_compress xxhash raid6_pq libcrc32c crc32c_generic hid_generic usbhid hid sd_mod crc32c_intel ahci xhci_pci libahci aesni_intel xhci_hcd aes_x86_64 crypto_simd libata igb cryptd glue_helper nvme usbcore scsi_mod i2c_piix4 i2c_algo_bit nvme_core dca usb_common gpio_amdpt gpio_generic [37342.777542] CPU: 4 PID: 14403 Comm: kworker/4:1 Tainted: G W 4.19.0-rc3-amd64 #1 Debian 4.19~rc3-1~exp1 [37342.777542] Hardware name: To Be Filled By O.E.M.
