Deadlocks with multiple applications on AMD RX 460 and RX 550 - Update 2

Wed Jan 31 23:57:52 UTC 2018

Hi everyone,

I am getting a new issue with amdgpu with RX460, that is, now I can
play any videos with Kodi or play web videos with firefox and run
OpenGL applications without running into any issues, however after
some uptime with XOrg even when almost inactive I get a kmalloc
allocation failure, normally followed by a GPU hang a while after the
the allocation failure.
I had a terminal window under Ubuntu Mate 17.10 and I was compiling
code when I got the kernel messages that can be found in attachment.

I am using the kernel as identified on my previous email, which can be
found below.

Regards,
Luís Mendes
