Yesterday I updated to 4.11.9 and so far everything is stable. I managed to reboot 6 times in a row with no issues. The kernel error is also gone from syslog.
I'm still not totally sure, because the original issue is a bit random, so that might have been just a good luck.
The jumpiness of mouse pointer shortly after connecting the dock remained, but this is a very minor issue (and might not be related to the freeze / panic problems).
