Radeon RX550 4GB stuck during kernel boot

[bjdooks-sifive]

The 2022.10 release works fine with a R7 4GB but my RX550 4GB is failing during boot.

Hello @bjdooks-sifive,

Thank you for reporting this issue to us.

Moreover, we reproduced it randomly, by doing several reboots, on RX550 4GB.

In addition, I’m currently working on a kernel update for the next FUSDK release, which contains some fixes for Radeon.

Kind regards,
Thomas

I'll try and test this on the latest release to see if it is fixed.
