Xorg hangs on startup (skylake)

[abi]

Hello,

I'm new to OpenBSD, but I'm old FreeBSD user. I've installed

OpenBSD 6.2 to XPS 13 /Skylake/ laptop (it runs FreeBSD with
unsignificant issues).

However, the system hangs (blackscreen, hard shutdown required) after
startx command.

No alterations to the system was made after install, setup excluded
games, laptop uses UEFI,

OpenBSD installed to usb stick.

I've done the following homework:

1. Tried vesa driver -> No screens found. (I have the same with FreeBSD)

2. Tried wsfb driver -> No screens found (If this is analog of FreeBSD's
scfb, it worked there)

3. Tried intel -> system hangs as with modesetting.

I expected difficulties, bot not too early :) I set
machdep.allowaperture=1 as X suggests.

Logs - https://pastebin.com/RkZz2b1y

The only errors are
error: [drm:pid0:i915_firmware_load_error_print] *ERROR* failed to load
firmware i915/skl_dmc_ver1.bin (-22)
error: [drm:pid0:i915_gem_init_hw] *ERROR* Failed to initialize GuC,
error -8 (ignored)

but they should be harmless

Please try a -current snapshot.

The same behaviour, system hangs after glamor initialization.

I've got the same problem on an HD620, I heard it's an ACPI problem that
needs to be patched.

Latest snapshot still has this bug. It's ongoing since 6.2 was
introduced unfortunately.

I see. Are there any PRs around I can check ?
