Short click on power button gives me a TTY like view prompting errors for nvme0 ext4 file system errors (i will post more exact text on next hangup) The hangups appear randomly, but often during shutting the lid or plugging in power cable, which makes me thing it might be something with ssd power states. For that reason i added grub parameters like "nvme_core.default_ps_max_latency_us=3000" (see Bug 1678184) and ended up fully disabling APST by setting it to 0, but the bug still occured. sudo nvme id-ctrl /dev/nvme0 yields: NVME Identify Controller: vid : 0x1c5c ssvid : 0x1c5c sn : EJ75N621210105PBR mn : PC300 NVMe SK hynix 1TB fr : 20005A00 rab : 1 ieee : ace42e cmic : 0 mdts : 5 cntlid : 0 ver : 10200 rtd3r : 90f560 rtd3e : ea60 oaes : 0 ctratt : 0 oacs : 0x16 acl : 3 aerl : 3 frmw : 0x16 lpa : 0x2 elpe : 254 npss : 4 avscc : 0x1 apsta : 0x1 wctemp : 361 cctemp : 363 mtfa : 0 hmpre : 0 hmmin : 0 tnvmcap : 0 unvmcap : 0 rpmbs : 0 edstt : 60 dsto : 1 fwug : 0 kas : 0 hctma : 0 mntmt : 0 mxtmt : 0 sanicap : 0 hmminds : 0 hmmaxd : 0 sqes : 0x66 cqes : 0x44 maxcmd : 0 nn : 1 oncs : 0x1e fuses : 0 fna : 0 vwc : 0x1 awun : 255 awupf : 0 nvscc : 1 acwu : 0 sgls : 0 subnqn : ioccsz : 0 iorcsz : 0 icdoff : 0 ctrattr : 0 msdbd : 0 ps 0 : mp:5.87W operational enlat:5 exlat:5 rrt:0 rrl:0 rwt:0 rwl:0 idle_power:- active_power:- ps 1 : mp:2.40W operational enlat:30 exlat:30 rrt:1 rrl:1 rwt:1 rwl:1 idle_power:- active_power:- ps 2 : mp:1.90W operational enlat:100 exlat:100 rrt:2 rrl:2 rwt:2 rwl:2 idle_power:- active_power:- ps 3 : mp:0.1000W non-operational enlat:1000 exlat:1000 rrt:3 rrl:3 rwt:3 rwl:3 idle_power:- active_power:- ps 4 : mp:0.0060W non-operational enlat:1000 exlat:5000 rrt:3 rrl:3 rwt:3 rwl:3 idle_power:- active_power:- sudo nvme get-feature -f 0x0c -H /dev/nvme0 yields: get-feature:0xc (Autonomous Power State Transition), Current value:00000000 Autonomous Power State Transition Enable (APSTE): Disabled Auto PST Entries .................
