Maybe your computer is experiencing an OOM (out-of-memory).

Maybe keep a system monitor visible (e.g. gnome-system-monitor or htop)
and keep an eye on the memory & swap usage. Does the freeze coincide with
high memory usage?

Also, can you still hear your disk spinning after a freeze?
(IIUC, that would indicate Linux is still issuing I/O to the disk
so Linux did not OOP? I'm not an expert on these matters though.)

What was the latest kernel version that worked for you?
