Public bug reported: Dell Vostro 15 7510 :lsb_release -crid Distributor ID: Ubuntu Description: Ubuntu 21.10 Release: 21.10 Codename: impish
Sporadically the laptop does not respond to keyboard or mouse input. The cursor still shows up. This may be associated with waking up from suspend. I can still get to a terminal with Ctl-Fn-Alt-F1. I see this in kern.log at about the time of the issue: Jan 24 11:54:58 brad-dell kernel: [14615.288956] PM: suspend exit Jan 24 11:55:02 brad-dell kernel: [14619.411849] wlp0s20f3: authenticate with 9c:3d:cf:71:af:77 Jan 24 11:55:02 brad-dell kernel: [14619.420838] wlp0s20f3: send auth to 9c:3d:cf:71:af:77 (try 1/3) Jan 24 11:55:02 brad-dell kernel: [14619.502877] wlp0s20f3: authenticated Jan 24 11:55:02 brad-dell kernel: [14619.505396] wlp0s20f3: associate with 9c:3d:cf:71:af:77 (try 1/3) Jan 24 11:55:02 brad-dell kernel: [14619.511548] wlp0s20f3: RX AssocResp from 9c:3d:cf:71:af:77 (capab=0x11 status=0 aid=6) Jan 24 11:55:02 brad-dell kernel: [14619.519475] wlp0s20f3: associated Jan 24 11:55:02 brad-dell kernel: [14619.582017] IPv6: ADDRCONF(NETDEV_CHANGE): wlp0s20f3: link becomes ready Jan 24 11:56:58 brad-dell kernel: [14735.585403] kauditd_printk_skb: 17 callbacks suppressed Jan 24 11:56:58 brad-dell kernel: [14735.585409] audit: type=1400 audit(1643050618.988:28): apparmor="DENIED" operation="open" profile="/usr/sbin/cupsd" name="/proc/sys/kernel/osrelease" pid=714 comm="cupsd" requested_mask="r" denied_mask="r" fsuid=0 ouid=0 Jan 24 11:56:58 brad-dell kernel: [14735.585544] audit: type=1400 audit(1643050618.988:29): apparmor="DENIED" operation="open" profile="/usr/sbin/cupsd" name="/proc/1/environ" pid=714 comm="cupsd" requested_mask="r" denied_mask="r" fsuid=0 ouid=0 Jan 24 11:56:58 brad-dell kernel: [14735.585554] audit: type=1400 audit(1643050618.988:30): apparmor="DENIED" operation="open" profile="/usr/sbin/cupsd" name="/proc/cmdline" pid=714 comm="cupsd" requested_mask="r" denied_mask="r" fsuid=0 ouid=0 Jan 24 11:57:52 brad-dell kernel: [14788.932312] ACPI Error: Thread 3295223488 cannot release Mutex [ECMX] acquired by thread 3475299392 (20210331/exmutex-378) Jan 24 11:57:52 brad-dell kernel: [14788.932333] Jan 24 11:57:52 brad-dell kernel: [14788.932336] No Local Variables are initialized for Method [_Q66] Jan 24 11:57:52 brad-dell kernel: [14788.932337] Jan 24 11:57:52 brad-dell kernel: [14788.932339] No Arguments are initialized for method [_Q66] Jan 24 11:57:52 brad-dell kernel: [14788.932340] Jan 24 11:57:52 brad-dell kernel: [14788.932345] ACPI Error: Aborting method \_SB.PC00.LPCB.ECDV._Q66 due to previous error (AE_AML_NOT_OWNER) (20210331/psparse-529) ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1958934 Title: laptop does not respond to keyboard or mouse input To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1958934/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
