I have a Dell XPS 9310 with 20.04 installed from the factory. Everything is working mostly fine, except that my computer freezes every now and then (about once a day). Most of the time, this happens when the screen is locked, though I have observed this while I am using the computer as well. How can I debug this issue? (I have already run memtest, and it found no memory errors.)
After some trial and error, I managed to fix my problem by upgrading the kernel version. I installed the package
linux-oem-20.04-edge and chose the most recent kernel when booting the system.
uname -s now tells me that I am running the version 5.10.0-1008-oem. I haven't experienced any freezes in about a month now.
