proposed patch
I'm having the same memory leak issue (though I kill the game when swapping starts so I did not experience kernel lock).
The attached patch seems to fix the problem; could you please test it with your setup ?
Also, I believe I fixed my kernel hardlocks by disabling my motherboard chipset's buggy IOMMU. The IOMMU for Intel VT-D on the ASUS P6T Deluxe motherboard is so buggy that it makes VT-d completely unusable on this motherboard. ASUS seems unwilling to patch their broken BIOS, maybe because the hardware is just broken.
Anyway, I can't reproduce the kernel hardlock with Linux 3.0-rc2 and the IOMMU disabled in the BIOS (VT-d set to disabled).
