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

Hi everyone,
I have some updates. I left the system idle most of the time during
the weekend and from time to time I played a video on youtube and
turned off the screen. Yesterday night I did the same and today
morning I checked the system and it got hung up during the night. This
time it took a lot longer to hang, but I think it was related to a
Flash animation add that was only present on the youtube page the last
time I switched off the screen. The amdgpu always seem to hang when
that flash animation is present, from all the crash attempts I have
made.
There is a memory leak according to kmemleak which I attach along with
the crash dmesg log.
The kernel and patches are the same as on my previous email. I ended
up not changing either the mesa version, nor the kernel version and
patches.
Regards,
Luís
