Bug ID: 65481 Summary: Page allocation failure errors on Trinity when playing a HL2 mod (i386 code on 64 bit kernel ) Product: Drivers Version: 2.5 Kernel Version: 3.12.0 git Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: laszlo.kertesz@gmail.com Regression: No

Created attachment 115641 --> https://bugzilla.kernel.org/attachment.cgi?id=115641&action=edit 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?
