I switched recently to elementaryOS. It just works fine but it crashes while watching YouTube videos. Sound starts repeating and machine become unresponsive. Or sound goes on but machine is unresponsive. In either case I have to restart. This happens almost everyday. Any recommendations?


I'm trying to read the crash dump. So far no luck! Based on this answer

I found offset with

sudo od -t x1 -A d /boot/vmlinuz-5.4.0-77-generic | grep "1f 8b 08"

which seems to be like 0018864 8f 1f 8b 08 00 00 00 00 00 02 03 ec dd 79 7c 15, therefore offset is 0018864+1. So creating the vmlinux like so;

sudo dd if=/boot/vmlinuz-5.4.0-77-generic bs=1 skip=18865 | zcat > /tmp/vmlinux-5.4.0-77

and extract dump into a folder

sudo apport-unpack /var/crash/_usr_lib_x86_64-linux-gnu_io.elementary.cerbere.1000.crash /tmp/crash/

produces below.

 $ ls -la /tmp/crash/

Still, I can't see the crash.

sudo crash /tmp/vmlinux-5.4.0-77 /boot/System.map-5.4.0-77-generic /tmp/crash/CoreDump

crash: /tmp/vmlinux-5.4.0-77: no debugging data available

Any ideas?

I found the solution in this answer https://askubuntu.com/a/796808/1198552 Created an intel.conf file as explained in that answer which solved my problem.
