The only splat that shows in either attachment is due to you not installing the
regulatory database that sets the channels etc. for your domain. I do not know
what it is called for your distro - it is wireless-regdb on mine. It is unlikely
that this is the cause of your problem, but who knows?

I installed the wireless-regdb package. The error message about
regulatory.db went away, but the system still froze.
I'll try the rtw_core parameter disable_lps_deep=1 now.

disable_lps_deep=1 did not help.

The patch set called "rtw88: add scan notify to firmware and refine fw_feature check" may have fixed this problem. I've been running commit 6ccdad5a58e18eac6b1335f05f94bf2b36146e00 from lwfinger/rtw88 for 3 days now with no freeze. It was impossible to go more than a few hours without a freeze before these patches.

Sounds good. I will keep porting the patches submitted to wreless-drivers-next
to the rtw88 repo at GitHub. I have no idea why this would preclude a system
freeze, but the Realtek guys might.

Larry

I spoke too soon. It does still freeze even with that patch set.
