I've been running commit 6ccdad5a58e18eac6b1335f05f94bf2b36146e00 from lwfinger/rtw88 for 3 days now with no freeze.

Nothing was logged, the CPU fan was spinning at a normal speed which is barely audible, and the mouse pointer didn't move anymore. Also, I tried the rtw_core option debug_mask=65535, which activates all the debug messages available, hoping to capture some useful information during the freeze, but with that option the freeze didn't happen. This suggests to me a timing problem, but who knows. I'm mostly clueless about kernel programming.
