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? > >One more thing, I believe that this happens most of the times > >(but not necessarily exclusively, but I don't have statistics) > >after resume (from suspend to ram). > > [MV] This is good to know. I wonder if this is related to the PCIe l used on your platform. Can you try to use PCIe link state management to L0s in your BIOS and see if the stability of your system improves? This is a locked down bios from Sony, I can't get access to these details, unfortunately.
