I am also getting this (or a similar) error on a different computer. Please note that this might be a longer story. I'll put some details before the dmesg.
drm:pid96852:intel_dp_aux_wait_done *ERROR* [drm] *ERROR* AUX C/DDI C/PHY C: did not complete or timeout within 10ms (status 0xa023003f) I don't know quite what to make of the overall story with this box. It cannot boot even to the BIOS or anything at all on the screen unless the DP is converted to a working HDMI port at the monitor. I truly mean nothing at all shows up. DP directly to DP fails. Not below. Then it works fine. Right now, I am booting into HDMI. When it gets to the xenodm screen, I have xenodm kill that DP->HDMI connection and switch over to the other DP port on the computer and into a DP port on my 4k monitor instead. I have to manually change to that port from my monitor. Annoying, but it works 97% of the time. I briefly used Windows 10 that came with the computer to verify a few things. The display port does carry sound. Not on OpenBSD. Back to just OpenBSD use. The beep speaker carries real audio. I cannot find a way to turn this off other than just using the headphone jack to grab the audio. However, the actual beep by itself sticks around no matter what. At some point I would like to add a video card that will let me run programs like chrome or iridium. Any recommendations? I am clueless how to figure out that question. Thanks for any help. Sorry if I missed making anything clear. Just ask for any clarifications. -- Chris Bennett OpenBSD 7.3 (GENERIC.MP) #1125: Sat Mar 25 10:36:29 MDT 2023 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP real mem = 34179473408 (32596MB) avail mem = 33124184064 (31589MB) random: good seed from bootblocks mpath0 at root scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.7 @ 0xec410 (93 entries) bios0: vendor Dell Inc. version "A23" date 06/25/2018 bios0: Dell Inc.
