i'm having some trouble with this driver. I have a dell latitude 7424 with an AMD RX550. upon installing onto a stock RHEL 7.8 os, the laptop locks up on the login screen. I can't Alt-FX, etc... The only way to fix is to blacklist AMDGPU, and then remove the driver. I've tried both the basic install and the pro and get the same results. Any suggestions?

If you can confirm that the GPU isn't an RX 550, your best bet is to update to RHEL 8.2 (if that's a possibility). I know for sure that RHEL 8.2 uses the 4.18 kernel which is new enough to have full open source driver support for your GPU. I'm not sure how much AMDGPU the Red Hat devs have backported to the Linux 3.10 kernel that RHEL 7.8 uses. Stock Linux 3.10 does not have AMDGPU period.
I'm not that keen on Red Hat, but upgrading to 8.2 is what I'd consider if I were in your position. Actually, I'd try out a CentOS live image based on RHEL 8.2 first to ensure it works and then upgrade .
I saw that the 7424 is sold with Ubuntu 18.04. It might not be your cup of tea, but any Ubuntu version or variant from then to now should work just fine for you if you aren't tied to RHEL for work reasons.

All the Latitude 7424's that I looked up come with either the discreet Intel graphics or an AMD RX 540 and the RX 540 does not have a supported AMDGPU-Pro Linux driver on AMD's website which explains why it doesn't work after you install this article's driver.

So, I have tried an elrepo kernel-lt, but it didn't have support for much of the other hardware in the laptop. I will try the kernel-ml next.
RHEL 8 isn't really an option for me, currently, but I will certainly try it. RHEL definitely backports a lot of the more modern hardware. I may put in a support request for this to see if there's anything that can be done in the near term, but they're not usually that fast on this type of update.
Ubuntu is not an option at all for me. all of our software is RPM based, and would take a significant amount of time to switch over.
So if I go with a 5.x kernel, I should be able to get amdgpu support without installing anything extra? I assume that I would then just use DRI_PRIME=1 to enable discrete graphics, yes?
Appreciate all the help!

The kernel-ls is based on Linux 4.4. You need something newer than 4.12 for decent AMD Polaris support. I suggest 4.15 or higher since that's when all the kinks in my RX 580 seemed to be worked out.
You should be good to go with the elrepo kernel-ml since it's a Linux 5.8 based kernel. And you assume correctly.
Good Luck.
