Issue #2714 has been updated by swildner.
I have looked at the patch, but it will not run with DEBUG_LOCKS in the kernel config. It gets stuck here right after entering the kernel from the loader, before the copyright messages and all. I guess it tries to kprintf() something at a point where kprintf() as such isn't usable yet. Have you tried it with DEBUG_LOCKS/DEBUG_LOCKS_LATENCY? Furthermore, I've changed the following things in the patch: * Move descr to the bottom of struct spinlock at Matt's request. * Change the argument order of SPINLOCK_INITIALIZER() to match spin_init()'s order, i.e. "descr" becomes the second argument. * Fix a broken kprintf() in usched_dfly.c. * Move some kprintf()s around for cosmetic reasons. * Adjust indent.
