I have been running my UR server on a DellR510 for a few years and decided that I wanted out of the datacenter hardware rat race.

 

 

I repurposed my docker box and picked up a new MB+CPU, this time an AMD with iGPU so that I can free up a slot on the board.

 

I've managed to get the array all back online but I ran into a problem in that you can't have the iGPU if enabling CSM and NOT booting into UEFI mode -which is how the R510 was booting for ages.

 

I renamed the efi- folder on the thumb drive, disabled CSM and was able to turn on the iGPU in BIOS. The UR boot screen comes up now and it starts the boot up process.

 

I can see where it finds the AMDGPU and starts the driver process. But it crashes with a calltrace and stops dead.

 

after a few seconds the screen scrolls like mad and ends up here;

 

I've searched Google and on here and have not found anything that makes it clear what the issue is or how to fix it.

 

Any ideas?

BUMP.

 

Any ideas anyone?

 

I doubt it but could this be a problem if I also have an Nvidia 1050ti installed at the same time? At the moment it's the only way I can get this server started with a functional screen attached. I tried with the iGPU on and set as primary but ended up with a blank screen and no webUI; I assumed the system locked up like it does now but with no screen there's no way of knowing it.

Is it possible that the CPU is too new for the current kernel in v6.12.113? Could the kernel bump in UR7 fix the issue?

Try blacklisting the AMD GPU:

I tried that and while it will boot up, the AMDGPU is not accessible to containers.

OK, I blacklisted it again, re-enabled it in the BIOS and the server came up with the AMD VGA in the devices list.

 

But now another issue, I went to install radeon-top and when it got to the last part, enabling the amd kernel mode (or something to that extent) the whole system locked up.

OK, so this is most likely down to the older kernel in URv6x. I'll have to wait till UR7 is released to take advantage of the APU in the AMD 8500G.

 

I had a chat with ich777 about Radeon-Top and he confirmed that installing Radeon-Top is the same thing as un-blacklisting the GPU. Which is not supported yet so that's why everything gets locked up.
