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 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
