Okay, bad news..gohan10 just panicked with the 'ufs_dirbad: bad dir' panic, and I'm pretty sure it was running 1.249.2.23 of vfs_subr.c, which is the version before both matt's vnlru change and the VOP_INACTIVE one (the version included in 4.5-RELEASE, in fact). The double fault last night was with 1.249.2.24 but when it rebooted it picked up the new kernel in the nfsroot image, which has 1.249.2.23, and then it panicked about 10 minutes later.
