I can now boot, compile a kernel, and reboot without catching any locking asserts. This means that we are safe at our current level of debugging, but we are certainly not out of the woods wrt VFS locking yet. If you have a crash test box I would appreciate it if you would enable this kernel option. If it catches any errors you will be droped into the debugger where you can get a backtrace (type: tr) and mail it to me && current@ to avoid dups. To disable the panic & print once you've hit a bug type the following in ddb: w vfs_badlock_print 0 w vfs_badlock_panic 0 And you will not see any more errors. Thanks!
