One of many error outputs:
https://pastebin.com/4hLJGKgP
the fix :
replace
/usr/lib/firmware/i915/kbl_dmc_ver1_04.bin
with
https://github.com/wkennington/linux-fi … er1_04.bin
I don't know if anyone else needs this. I've searched for the solution and couldn't find it until now
Driver was enabling dc_state even while plugged in, unplugging laptop fixed issues, any attempt to go
into lower power state while on ac caused kernel panic.

Have you reported the issue upstream? https://gitlab.freedesktop.org/drm/inte … -i915-bugs
How did you arrive at your solution? What is the difference in the firmware?
Edit:
The kbl_dmc_ver1_04.bin you linked to and the firmware arch supplies are the same:
sha256sum /tmp/kbl_dmc_ver1_04.bin
2cde41c3e5ad181423bcc3e98ff9c49f743c88f18646af4d0b3c3a9664b831a1 /tmp/kbl_dmc_ver1_04.bin
sha256sum /usr/lib/firmware/i915/kbl_dmc_ver1_04.bin
2cde41c3e5ad181423bcc3e98ff9c49f743c88f18646af4d0b3c3a9664b831a1 /usr/lib/firmware/i915/kbl_dmc_ver1_04.bin
