Unfortunate for sure, but certainly understandable.
I don't know what the timeline is for enabling PAL in earlier GPUs (it supports everything back to SI AFAIK) but I'll ask if it is worth installing on SI with the PAL option selected to see if/how it works. In a lot of cases the main obstacle to switching code paths quickly is more about the testing/tuning/certification effort than about "making it run".

When it comes to certifcations, as i see here for Maya 2018.3 Windows is there marked as Tested (not Certified) for Radeon R9 280/X with Crimson Edition 16.6.2 (nearly 2 years old driver for a new version of Maya sounds like a copy/paste to me ) with all APIs:

While for Linux only AMD workstation cards are there, so not sure... maybe AMD only supports workstation cards on Maya for Linux or they just do certifications for workstation cards for Linux, but not Testing of consumer cardsLast edited by dungeon; 04 May 2018, 05:35 PM.

Can you provide some more details about your system so we can try to reproduce? Also, any log files you can provide from the failed boot would be helpful. If you can file a bug report at the freedesktop.org bugzilla (DRM/AMDgpu or DRM/AMDgpu-pro), even better.
