Description Mowley 2018-09-14 17:37:08 UTC

Running Arch Linux on AMD FX-8350 with Radeon Pro WX-5100 GPU

version 2.4.94-1 of libdrm caused blender to crash with the following error

amdgpu_device_initialize: amdgpu_query_info(ACCEL_WORKING) failed (-9)

downgraded to 2.4.93-1 as a temporary fix.

Comment 1 Mowley 2018-09-14 17:38:09 UTC

can provide more info if required but was unsure as to what specifically I should attach in order to help.

Comment 2 Michel Dänzer 2018-09-17 09:44:13 UTC

Can you bisect?

Comment 3 Michel Dänzer 2018-09-17 09:58:08 UTC

Please attach the Xorg log file and the output of dmesg and xrandr.

I'm guessing that my XOrg log file would now be superfluous?

Yeah, actually comment 3 was intended for another bug report, sorry.


Christian, any idea how the commit below could cause this?

-EBADF means the file descriptor number is already closed.

So maybe the application is trying to open/close the device multiple times and we have a bug in amdgpu_device_free_internal?
