Maybe you could try with some other debugging options? E.g. since lockdep doesn't help - turn this off. Instead try some others, like these: > # CONFIG_DEBUG_SPINLOCK_SLEEP is not set > # CONFIG_DEBUG_LOCKING_API_SELFTESTS is not set > # CONFIG_DEBUG_KOBJECT is not set > # CONFIG_DEBUG_HIGHMEM is not set > # CONFIG_DEBUG_VM is not set > # CONFIG_DEBUG_LIST is not set > # CONFIG_DEBUG_SG is not set > # CONFIG_BOOT_PRINTK_DELAY is not set > # CONFIG_DEBUG_STACKOVERFLOW is not set > # CONFIG_DEBUG_STACK_USAGE is not set > # CONFIG_DEBUG_RODATA is not set Regards, Jarek P.
