I was just running 6.5-release. When I get a minute this afternoon, I will try the latest snapshot and see if I can get video working. I'll send the dmesg to dm...@openbsd.org.

I don't think there is a whitelist at all on this system regarding wireless cards. It's a work laptop and is very common that we have to replace the wireless cards on laptops. We had a spare broadcom which won't work either on FOSS but it was detected and boots without problems while I was waiting for the AC 8265. Probably atheros cards would be other option, the Intel would cost now like 25€ online.

There is no support for newer Intel wireless like the 9260 the T495 has. The version of amdgpu in the tree does not include support for picasso APUs (Ryzen 3xxx) https://en.wikichip.org/wiki/amd/cores/picasso or whatever raven2 works out to be. It is also not enabled by default just yet. If anyone wants to have a Ryzen thinkpad work in the short term the current A series A285/A485 and similar generation E series require less work. Suspend/resume doesn't work right on them currently. They mostly ship with RTL8822BE wireless which there is no support for but this can be replaced with an Intel 8265 which is in the bios whitelist and is supported by iwm(4).

Re: Lenovo w/ AMD Ryzen CPU
I just ordered some E495s (not 'T', but pretty similar). I think they're supposed to arrive today. I'll do a test boot and send in a dmesg.

First, less flaws were identified with AMD's implementation of speculative execution. That means that there are less mitigations to slow down the system. Whether there are unidentified flaws, that's another issue.. Second, the amdgpu driver was just imported to OpenBSD 6.5-current. That means you'll have graphics support. Combined with the recent improvements to xhci and wi-fi driver improvments (well, mostly intel), support for modern laptops has never been better. Chris
