I've been running freeze free for about 5-6 weeks now. I tried a lot of
stuff suggested in the comments - new kernels, kernel options, removing
pulseaudio, etc...

Some of them resulted in no freeze for about a week but they always came
back.

Finally I read in
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/546871 about
problems with freezes with Atheros network cards. I have a Atheros in my
laptop. I found that if I disable the wireless adapter (I use a wired
connection 99% of the time anyway) via Network Manager that I get no
freezes.

Searching for more issues with Arheros leads to bug 426130. I haven't tired the backport fix listed there yet, but I'm confident it is something in the Network stack for me:
