Hi,

I am using the radeon r600 driver on an integrated AMD GPU listed by lspci as [AMD/ATI] Wrestler [Radeon HD 7340]. It is the GPU part of the AMD E2-2000 APU.

I am on an up-to-date x86-64 Arch Linux [testing] system:

*** mesa 11.1.0 xf86-video-ati 7.6.1 xorg-server 1.18.0 libdrm 2.4.65 llvm 3.7.0 linux 4.3.3 (corresponding 32 bit versions are installed where applicable) ***

While trying to play the Steam game "Gods Will Be Watching", I encounter a hang at the start of chapter 1 with no progress being made at the black screen showing "One Year Ago". This happens whenever I try to load the saved game at that point. Enabling LIBGL_ALWAYS_SOFTWARE allows the game to progress (but at an extremely low frame rate, of course). It does not matter whether I am using DRI2 or DRI3.

Attached is the strace output with me killing the process at the end. I currently do not have debug versions of the libraries installed, so the gdb backtrace is pretty useless, and I am not sure if I captured the right moment: *** #0 0xf7fd9be5 in __kernel_vsyscall () #1 0xf77eda2b in pthread_cond_wait@@GLIBC_2.3.2 () from /usr/lib32/libpthread.so.0 #2 0xf78f6d8d in pthread_cond_wait@@GLIBC_2.3.2 () from /usr/lib32/libc.so.6 #3 0xe0a10592 in ??

Thank you for your work on the open source Linux graphics stack. It is very much appreciated.
