Hi, Lately, I've spent time debugging a problem with the DRM locking code on Alpha. http://bugs.freedesktop.org/show_bug.cgi?id=16549 After searching through the userspace components (libdrm, mesa, xserver) and not finding any relevant changes, I think the problem must be located in the kernel. David Airlie pointed me to possibly relevant commits to alpha's system.h which contains cmpxchg. http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=history;f=include/asm-alpha/system.h;h=afe20fa58c990927fd10c5e94d41fe4d8d9eee8a;hb=HEAD Can anyone see where the bug is located?
