Comment # 9
on bug 109001
from Matt Garman
I too am having the same problem. After the screen blanks, the system is barely usable: pauses/freezes randomly. If I switch to a virtual (text) console, everything works as expected. Switching back to X usually causes X to crash, kicking me back to the login screen. Usually after I re-login, the pauses are gone. Sometimes it takes a second try. Every now and then, though, the pausing/freezing won't go away, and a reboot is required. I am using Manjaro, which is based on Arch, so fairly similar to the original poster. Kernel 4.19.12-2-MANJARO. In addition to the error log lines already reported: [32952.381123] [drm:dm_vblank_get_counter [amdgpu]] *ERROR* dc_stream_state is NULL for crtc '1'! [32952.381201] [drm:dm_crtc_get_scanoutpos [amdgpu]] *ERROR* dc_stream_state is NULL for crtc '1'! I also have the following kernel trace in dmesg: [24708.647186] WARNING: CPU: 2 PID: 638 at drivers/gpu/drm/amd/amdgpu/../display/dc/core/ dc_link.c:1570 core_link_enable_stream+0x657/0xb90 [amdgpu] [24708.647187] Modules linked in: iptable_mangle xt_CHECKSUM iptable_nat ipt_MASQUERADE n f_nat_ipv4 nf_nat xt_conntrack nf_conntrack nf_defrag_ipv6 nf_defrag_ipv4 libcrc32c ipt_R EJECT nf_reject_ipv4 xt_tcpudp tun bridge stp llc devlink ebtable_filter ebtables ip6tabl e_filter ip6_tables iptable_filter rpcsec_gss_krb5 auth_rpcgss nfsv4 dns_resolver nfs loc kd grace sunrpc fscache cmac bnep nct6775 hwmon_vid amdkfd amd_iommu_v2 amdgpu arc4 iwlmv m edac_mce_amd snd_hda_codec_hdmi kvm_amd snd_hda_intel ccp mac80211 rng_core kvm snd_hda _codec btusb chash btrtl gpu_sched btbcm fuse irqbypass ttm snd_hda_core btintel snd_hwde p iwlwifi crct10dif_pclmul drm_kms_helper crc32_pclmul bluetooth snd_pcm ghash_clmulni_in tel pcbc drm snd_timer mousedev cfg80211 igb agpgart syscopyarea sysfillrect aesni_intel wmi_bmof [24708.647214] ecdh_generic snd sysimgblt aes_x86_64 i2c_algo_bit crypto_simd cryptd inp ut_leds glue_helper fb_sys_fops soundcore dca rfkill pcspkr sp5100_tco i2c_piix4 k10temp wmi evdev mac_hid gpio_amdpt pinctrl_amd pcc_cpufreq acpi_cpufreq sg crypto_user ip_table s x_tables ext4 crc32c_generic crc16 mbcache jbd2 fscrypto sr_mod cdrom sd_mod hid_generi c usbhid hid ahci libahci libata xhci_pci scsi_mod xhci_hcd crc32c_intel [24708.647233] CPU: 2 PID: 638 Comm: Xorg Tainted: G W 4.19.12-2-MANJARO # 1 [24708.647234] Hardware name: To Be Filled By O.E.M.
