full dmesg showing the errors

I use a 64 bit Debian system with kernel (mainline, now 3.12.0-10928-g527d151),
mesa, llvm, drm, xf86-ati compiled from git on an A8-5500 APU (radeon/r600
driver, .
While i played a Half Life 2 mod called No more room in hell on Steam (32-bit
application) i noticed that dmesg is full of errors like:

Repeated many times. And the last error messagesss were only:

[drm:radeon_cs_ioctl] *ERROR* Failed to parse relocation -12!

I didnt observe any adverse effects on system stability.
This is some type of memory allocation issue, maybe related to 32 bit code
running on 64 bit kernel?
