Status in linux package in Ubuntu: Incomplete Bug description: Kind of a follow up/extension to https://bugs.launchpad.net/ubuntu/disco/+source/linux/+bug/1858832 == Original Bug Report (for the most part, still holds true) == RELEASE=19.3 CODENAME=tricia EDITION="Cinnamon" DESCRIPTION="Linux Mint 19.3 Tricia" DESKTOP=Gnome TOOLKIT=GTK NEW_FEATURES_URL=https://www.linuxmint.com/rel_tricia_cinnamon_whatsnew.php RELEASE_NOTES_URL=https://www.linuxmint.com/rel_tricia_cinnamon.php USER_GUIDE_URL=https://www.linuxmint.com/documentation.php GRUB_TITLE=Linux Mint 19.3 Cinnamon My home dir is mounted through nfs on a local server via nfs4 and krb5i. When stressing the mounted directory or its sub-directories (sometimes starting firefox, sometimes starting thunderbird, nearly guaranteed when compiling, sometimes the login itself), it will eventually lead to the following stack-trace. The corresponding process is then stuck and accessing the mounted directory (like calling ls) easily yields further and similar stack trace and causing the process to also stuck. Currently I am running an AMD 3950x on a ASUS Crosshair VII Hero Wifi (chipset x470). I installed Ubuntu 20.04 LTS Desktop to check if the newer kernels (5.4 + 5.6) work without issues, but sadly, they **do not**. With a little compile-stress-test, I have tested the following kernels which seem to run fine: * 4.15.0-69 * 4.15.0-70 * 4.15.0-72 * 5.0.0-32 * 5.0.0-47 (current daily driver, runs without a hassle, max test length >7d - I am writing this bug report on it) But the following kernels do not run stable: * 5.3.0-51 (Linux Mint 19.3 HWE) * 5.4.0-28 (Ubuntu 20.04) $ lspci | grep -i ether 06:00.0 Ethernet controller: Intel Corporation I211 Gigabit Network Connection (rev 03 $ mount | grep filer filer:/ on /share type nfs4 (rw,noatime,vers=4.0,rsize=1048576,wsize=1048576,namlen=255,soft,proto=tcp,timeo=600,retrans=2,sec=krb5i,clientaddr=192.168.3.55,local_lock=none,addr=192.168.2.33) filer:/home/michael on /share/home/michael type nfs4 (rw,noatime,vers=4.0,rsize=1048576,wsize=1048576,namlen=255,soft,proto=tcp,timeo=600,retrans=2,sec=krb5i,clientaddr=192.168.3.55,local_lock=none,addr=192.168.2.33) $ cat /etc/fstab | grep -i filer filer:/ /share/ nfs4 nfsvers=4,sec=krb5i,rw,x-systemd.automount,soft,intr,tcp,noatime 0 0 --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu27 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: rootmw 2299 F.... pulseaudio /dev/snd/controlC2: rootmw 2299 F.... pulseaudio /dev/snd/controlC1: rootmw 2299 F.... pulseaudio /dev/snd/controlC3: rootmw 2299 F.... pulseaudio CRDA: Error: command ['iw', 'reg', 'get'] failed with exit code 1: nl80211 not found.
