Good catch Mauricio! 1. "nomodeset" did not help. 2. "dis_ucode_ldr" succeed.
The logs after the successful boot are attached. What can I do to make the boot use "dis_ucode_ldr" by default? ** Attachment added: "var_log3.tar.gz" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1895458/+attachment/5413022/+files/var_log3.tar.gz -- 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.
