Stumped again, dual GPU Linux issue
My Ryzen system (R7-1700, Gigabyte AB350 Gaming, RX-480 and RX-470) will not boot into Linux if I have both GPUs installed. If I unplug the RX-470 all is well. I get a variety of kernel panics. I have tried live CDs for ubuntu, debian, manjaro, mint. I finally installed Manjaro and updated it to the very latest kernel, 4.17 and it still gets a kernel panic booting up with both cards installed. I have also updated the BIOS, went to default settings on the motherboard, and even went back to stock BIOS on the GPUs. All this works fine in Windows, and has for months, which I am apparently stuck with on this system for now.
The last few messages are:
Kernel panic - not syncing: Fatal exception in interrupt
AMD-Vi: Completion-Wait loop timed out
Kernel Offset: 0x27000000 from 0xffffffff81000000 (relocation range: 0xffffffff800000000-0xffffffffbfffffff)
I don't know that I ever ran two AMD cards in this system under Linux, for sure I was running multiple NVIDIA cards in the past. But it has been running Windows mining for quite some time. I was giving up the mining thing and thought I would get this back up in Linux and Boinc. If any of you Linux gurus have any ideas I would appreciate it.
