Subject: Lockdep problem
Date: Sat, 8 Mar 2008 20:10:56 +0300 [thread overview]
Message-ID: <bc64b4640803080910w3c2905d6gd17357aafa7b2db9@mail.gmail.com> (raw)
Hi,
I've ran into the lockdep problem: I'm hitting the condition at the
lockdep.c:2437:
if (DEBUG_LOCKS_WARN_ON(id >= MAX_LOCKDEP_KEYS))
return 0;
What does it mean and how to overcome it? Dumbly increasing constants
at kernel/lockdep_internals.h didn't help.
The warning is pretty fatal for me because it happens when I'm locking
clocks lock, so when serial console output calls
clk_enable/clk_disable the kernel deadlocks.

With best wishes
Dmitry
