My test box with the Promise ATA RAID in it is getting really upset by a devfs vnode and finally panics with a trap 12 with syncer following a null pointer. Note this is with the install disc. I can put 5.1-R back on and do a remote installworld versus -current pretty easily, and can attempt to build a tree for RELENG_5_2. This is the copy from the serial console.
