Pinebook 1080p / KDE Neon freezes every 5-10 min

[pyrrhumain]

(reposting this here in case 'quick reply' was the wrong place)

HELLO and thanks for the replies. I apologize the the lack of response, but 1) this is a side project for me, and 2) I wanted to get some evidence before I asked for more help.

In particular, I wanted to collect the output from dmesg and /var/log/syslog from more than one incident.

I ended up collecting the last 80-100 lines of output from syslog and dmesg after each of 8 freezes. The last one happened after I executed 'pkcon refresh' and 'pkcon update' and restarted -- sorry, jezek.)

The following lines appeared consistently at the end of syslog and dmesg:

I don't have the background to interpret any of this, but I'm hoping someone else does.

Any ideas?

Thanks in advance, R.M.
