So I have arch running on a mining rig and everything was running fine until I tried adding a 5th GPU. On boot I get an error that says hw_init of IP block failed -110. I've switched around risers and cards and the same thing happens.
Interestingly, if I switch my new card to another PCI-E slot, it still doesn't run but the one switched over will. It's almost as if arch is keeping track of which GPUs I've had and not running the new one.
I found this recent thread that displays the issue but it seems it may just be a kernel bug, in which case, do I have to just wait for a patch to the linux kernel?
