- 5.4.0-26 good - 5.4.0-48 bad Let's try 5.4.0-37. Could you please download its .deb files, install with 'dpkg -i *.deb', and test it without dis_ucode_ldr? This list includes linux-modules-extra and headers packages; please feel free to remove if you don't have them installed. $ wget https://launchpad.net/~canonical-kernel-security- team/+archive/ubuntu/ppa/+build/19402449/+files/linux-{image- unsigned,modules,modules- extra,headers}-5.4.0-37-generic_5.4.0-37.41_amd64.deb https://launchpad.net/~canonical-kernel-security- team/+archive/ubuntu/ppa/+build/19402449/+files/linux- headers-5.4.0-37_5.4.0-37.41_all.deb $ sudo dpkg -i linux-*_5.4.0-37.41_*.deb Links from: https://launchpad.net/~canonical-kernel-security-team/+archive/ubuntu/ppa/+build/19402449 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1895458 Title: Computer freezes on kernel 5, works on kernel 4 Status in linux package in Ubuntu: Confirmed Bug description: The computer works with kernel Ubuntu 4.15.0-112.113-generic 4.15.18.
