Hi,
I have installed DragonflyBSD 6.2.1 on my Thinkpad T460 with Hammer2.
But I discoverd the following problem:
- browsing with Firefox is incredibly slow, even moving the browser window jerks
- htop(1) shows that one of four CPU cores is also always at 100%
- I found the following message in via dmesg:
% dmesg | grep error
dm_target_error: Successfully initialized

I use the standard kernel and just load the iwm and i915 modules via /boot/loader.conf and /etc/rc.conf.
Does anyone has an answer or hint how to fix this?
Best,
Fritjof
