I installed the following deb packages for kernel 5.4.51 https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.4.51/amd64/linux- headers-5.4.51-050451_5.4.51-050451.202007090834_all.deb
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.4.51/amd64/linux- image- unsigned-5.4.51-050451-generic_5.4.51-050451.202007090834_amd64.deb https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.4.51/amd64/linux- modules-5.4.51-050451-generic_5.4.51-050451.202007090834_amd64.deb I was unable to install https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.4.51/amd64/linux-headers-5.4.51-050451-generic_5.4.51-050451.202007090834_amd64.deb which appeared to match the naming convention of the older kernel files, as its dependencies were not satisfied. I selected kernel 5.4.51 using the grub bootloader, but the boot process was still very slow due to the multiple error messages from the sound system. I have attached the dmesg file obtained during boot-up.
