Subject: Re: Linux 2.6.24-rc7: sparc64: WARNING: at kernel/lockdep_proc.c:267 lockdep_stats_show()

Hello,

	Got this when doing usual looping over /proc entries on fresh test kernel:

WARNING: at kernel/lockdep_proc.c:267 lockdep_stats_show()
Call Trace:
 [0000000000492704] lockdep_stats_show+0x6ac/0x6c0
 [00000000004eb4b4] seq_read+0x5c/0x340
 [000000000050b2bc] proc_reg_read+0x64/0xa0

 [00000000004062d4] linux_sparc_syscall32+0x3c/0x40
 [0000000000012ff4] 0x12ffc

and this would be:

#ifdef CONFIG_DEBUG_LOCKDEP
        DEBUG_LOCKS_WARN_ON(debug_atomic_read(&nr_unused_locks) != nr_unused);
#endif

Regards,

	Mariusz
