I'm learning OpenBSD on an older laptop from a company called Hannspree. The installation went great and everything seemed fine, but when the system boots it quickly starts to slow down and eventually hangs with a flashing screen before the log in prompt. The problem goes away when I disable acpimadt.
I'm running well enough for my purposes at the moment, but I was encouraged by some helpful redditors to post this problem here. Apparently, learning to productively participate with the mailing list is an essential openbsd lesson and hopefully someone knows what I've done wrong or this can help a dev fix a bug. I've uploaded a video of the problem here : https://www.youtube.com/watch?v=ALN00Y8w0l8 dmesg below: OpenBSD 5.5 (GENERIC.MP) #315: Wed Mar 5 09:37:46 MST 2014
