If the issue is still present using 4.18.12-arch1-1-ARCH or 4.19-rc7 please report the issue upstream see https://www.kernel.org/doc/html/latest/admin-guide/reporting-bugs.html for details of how to report upstream.

I've begun identifying the problem and to whom's attention it should be brought on the kernel dev side, but as the issue was just assigned to people, please see the attached additional kernel and wlan crash logs. Both happened on 4.18.12-arch1-1-ARCH. From what I can gather it is related to the rtl8192e driver.

The kernel is tainted which is an issue for upstream reporting. I would suggest blacklisting all out of tree modules and see if the issue still occurs.
