Subject: [BUG] AMD Radeon Pro 5600M with 8GB of HBM2 memory shows blank screen on Linux
Date: Mon, 26 Dec 2022 10:44:06 +0000	[thread overview]
Message-ID: <3AFB9142-2BD0-46F9-AEA9-C9C5D13E68E6@live.com> (raw)

The AMD Radeon Pro 5600M with 8GB of HBM2 memory GPU is found in MacBook Pro 16 inch, 2019 (MacBookPro16,4).

The GPU fails to work on Linux, thus a blank black screen gets displayed on boot.

If nomodeset is added as a kernel parameter, we are able to access Linux easily.

The link below contains the journalctl of the failed boot :-
