Definitely better. I still get occasional hickup but normally they
are just temporary, and no intervention is needed.

> [MV]  I'm going through this log -- don't have a root cause for this yet, but getting closer to it. I see in this log that authentication is timing out. It appears that the driver sent out the authentication frame, and received some frame OTA, but I can't tell what it received from just the dmesg log. I'd like some trace-cmd logs from you. Is it possible for you to collect a trace-cmd log and send over the binary to me?

WHat do you mean with trace-cmd? I don't have a "trace" utility installed,
only strace and ltrace AFAIR. And then, what should be traced?

This is a locked down bios from Sony, I can't get access to
these details, unfortunately.

Best wishes
