Two weeks ago, I switched to Xunbuntu 19.04, by: - changing the lines in the /etc/sources.list - running apt-get dist-upgrade Since then, the computer randomly totally freezes ~twice a day. Even after another dist-upgrade this morning... When I say "totally freezes", I mean: - Mouse is froozen, if there was sound playing (be it movie or music, played either with mplayer or vlc), then the last 1/2 second loops indefinitely - CTRL-ALT-Fn do not work - There's nothing in the logs: kern.log, syslog, dmesg... appart some garbage chars (like ^@^@^@...) that sometimes gets appended in syslog at crash time. - Even when activated Magic SysReq (ALT-SysReq-RSEIUB) do not work - Alt-SysReq 1 + Alt-SysReq t do not create anything in /var/crash (there are some files for qemu & xfce4-panel, that I already reported) - Following https://wiki.ubuntu.com/Kernel/CrashdumpRecipe , I installed linux-crashdump, and verified it correctly sets the boot line option, but nothing gets created in /var/crash when computer crashes (apart a kexec_cmd file that simply lists the boot line args). - Quick (2/3 sec) press on the power button does nothing - Long (10 sec) press on the power button is the only way to regain control... - I've tried to run Memtest86+ (even if I'm sure RAM is not the problem as it started occurring only after dist-upgrade to 19.04), but the system is UEFI, so option is not in the grub menu. I'll try to make a USB stick to test the RAM FYI, the internal wifi card (rtl8723) has always caused troubles: HD write slowdowns, audio device locks, etc (from what I guess, it overfills some internal bus...). So I deactivate it at boot by removing the module, and I use another external Wifi dongle (rt2800usb) $ uname -a Linux gmuller-X751LAB 5.0.0-16-generic #17-Ubuntu SMP Wed May 15 10:52:21 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux # Note: crashes occurred also with 5.0.0-15 Does anyone has any hints/tips on how I could get more info & target where the problem comes from? because as-is the computer is just unusable... In the attached log files, the crash occurred right before my manual reboot at 15:17:24 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1833474/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
