Hi,
I get the following Oops after trying to start nscd from YaST on an Athlon64-based box
(compiled with CONFIG_DEBUG_SPINLOCK=y):

----------------------------------------
.. [<ffffffff80352706>] .... _spin_trylock+0x16/0x60
.....[<ffffffff8010fc81>] .. ( <= oops_begin+0x11/0x60)
.. [<ffffffff80352706>] .... _spin_trylock+0x16/0x60
.....[<ffffffff8010fc81>] .. ( <= oops_begin+0x11/0x60)
It causes other Oopses to appear in an infinite loop (some of them are attached).
This is 100% reproducible, and 2.6.13-rc5 is not affected.
Greets,
