Description rozhuk.im 2019-01-16 23:51:19 UTC
I have ASIX AX99100 uart/serial controller with 2 ports, it works on 11.2 and don't work on 12.0 - no data received.
It used for communicate with old APC smart, by sysutils/apcupsd.

Also, I'm not sure that FreeBSD bug, but on ryzen platform (x370 taichi + 1300x) system freeze (and not respond until reset) with this controller after 10-20 minutes.
On AM1 based platform no freeze.
