I tried to build new drivers from v4l hg for 06/08/10 and when I tried 
to load drivers I got a kernel oops. Kernel is 2.6.34 64bit for amd cpu

See:
http://article.gmane.org/gmane.linux.drivers.video-input-infrastructure/20198
http://article.gmane.org/gmane.linux.drivers.video-input-infrastructure/19904

The Oops appears to be in the same place as the Oops I analyzed in the
second link.  However, your compiler, like mine, decides to code the
comparison against RC_DRIVER_SCANCODE (which is 0) first:

	4f: 83 3a 00   cmpl   $0x0,(%rdx)    <---------- Oopsing insn

Right about here:

http://linuxtv.org/hg/v4l-dvb/file/23492745405c/linux/drivers/media/IR/ir-sysfs.c#l226


As mentioned in the first link, please try the patch found here:
