a few things to try. first is to use the kernel flag iommu=pt or iommu=off
second is to check if there are any available bios updates. I remember reading about similar issues with ryzen mobile but I also remember solutions being found so I’ll update when I find what I’m talking about.
edit here’s the thread
Hey all. I picked up the ThinkPad E585, thought I would do a mini review of the laptop now that I’ve had some time to play around with it. This will not be a thorough review, just some general thoughts and info. I intend to edit it as I continue tinkering with it.
Specs:
Ryzen 5 2500U with Vega 8 Mobile graphics
16GB (8+8 dual channel) DDR4 2400
256GB m.2 NVMe SSD
(mod) 500GB SSD for dual booting
1080P IPS
TL;DR: I like the laptop. Good build quality, decent display, good performance. Battery life isn’t great… around 4 hours give or take. Linux works well with the latest kernel/mesa… only bluetooth doesn’t work.

Note: I got cinebench GPU score slightly over 40 on another run… not pictured here.
Here are some general thoughts:
Chassis/Build Quality:
Very happy with the laptop in terms of quality. It feels very solid, no creaks or pops, no keyboard flex. Everyone seems to complain about the E-series thinkpads being cheap but I was pleasantly surprised. Top is aluminum, the rest is plastic. The lid does attract fingerprints pretty bad, but it’s not a big issue.
Keyboard/Trackpad:
Disclaimer: I’ve never used a laptop with windows precision trackpad drivers, so I can’t compare to that. This laptop uses a synaptic trackpad and it seems to track well. Everything works as expected in both Windows and linux. Clicking feels VERY nice on the bottom trackpad buttons… it’s like a muffled clicky sound which is really satisfying. Difficult to explain. I like the keyboard a lot. Th…
