The system ran for a whole day without crashing and it had gone into screen lock multiple times but did not crash. Yesterday night I disconnected power and closed laptop. Today when I opened, the lock screen came up, I entered password and it crashed at that point.
The screen scrolled too much and I couldn't get a screenshot. However the first line was error while async write back metadata I also recollect the third line which said failed to set APST feature I think I saw -19 after that, not sure though. I ran this sudo nvme id-ctrl /dev/nvme0 NVME Identify Controller: vid : 0x15b7 ssvid : 0x15b7 sn : 205135806243 mn : WDC PC SN530 SDBPMPZ-512G-1101 fr : 21160001 rab : 4 ieee : 001b44 cmic : 0 mdts : 7 cntlid : 0x1 ver : 0x10400 rtd3r : 0x7a120 rtd3e : 0xf4240 oaes : 0x200 ctratt : 0x2 rrls : 0 cntrltype : 1 fguid : crdt1 : 0 crdt2 : 0 crdt3 : 0 oacs : 0x17 acl : 4 aerl : 7 frmw : 0x14 lpa : 0x1e elpe : 255 npss : 4 avscc : 0x1 apsta : 0x1 wctemp : 353 cctemp : 358 mtfa : 50 hmpre : 51200 hmmin : 823 tnvmcap : 512110190592 unvmcap : 0 rpmbs : 0 edstt : 57 dsto : 1 fwug : 1 kas : 0 hctma : 0x1 mntmt : 273 mxtmt : 358 sanicap : 0x60000002 hmminds : 0 hmmaxd : 8 nsetidmax : 0 endgidmax : 0 anatt : 0 anacap : 0 anagrpmax : 0 nanagrpid : 0 pels : 1 sqes : 0x66 cqes : 0x44 maxcmd : 0 nn : 1 oncs : 0x5f fuses : 0 fna : 0 vwc : 0x7 awun : 0 awupf : 0 nvscc : 1 nwpc : 0 acwu : 0 sgls : 0 mnan : 0 subnqn : nqn.2018-01.com.wdc:guid:E8238FA6BF53-0001-001B448B484DAFF7 ioccsz : 0 iorcsz : 0 icdoff : 0 ctrattr : 0 msdbd : 0 ps 0 : mp:3.50W operational enlat:0 exlat:0 rrt:0 rrl:0 rwt:0 rwl:0 idle_power:0.6300W active_power:2.10W ps 1 : mp:2.40W operational enlat:0 exlat:0 rrt:0 rrl:0 rwt:0 rwl:0 idle_power:0.6300W active_power:1.60W ps 2 : mp:1.90W operational enlat:0 exlat:0 rrt:0 rrl:0 rwt:0 rwl:0 idle_power:0.6300W active_power:1.50W ps 3 : mp:0.0250W non-operational enlat:3900 exlat:11000 rrt:3 rrl:3 rwt:3 rwl:3 idle_power:0.0250W active_power:- ps 4 : mp:0.0050W non-operational enlat:5000 exlat:39000 rrt:4 rrl:4 rwt:4 rwl:4 idle_power:0.0050W active_power:- I am going to try to replicate the error by running through the same scenario. Allowing the laptop to suspend while power disconnected and then try to login after that. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1927866 Title: Root filesystem becomes readonly frequenty freezing system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1927866/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
