Description

Metro 2033 Redux hangs when the certain combination of mesa version, kernel version and kernel configuration is used. This is always happen on loading screen.

I have done some tests using integrated benchmark (benchmark.sh):

linux-4.14.x + mesa-7.3.x = OK
linux-4.14.x + mesa-8.0.x / mesa-8.1.x = hang
linux-4.17.x with CONFIG_TRANSPARENT_HUGEPAGE=y = OK
linux-4.17.x with CONFIG_TRANSPARENT_HUGEPAGE=n + mesa-8.0.x / mesa-8.1.x = hang

When the hang occur, it is causes massive slowdown of all other graphical applications. With 4.14 kernels the game process is unkillable so it hangs somewhere in the kernel space. With 4.17 kernels it can be killed but this takes some time.
