2.4.x-ac? SMP on a Via 82c694X

Is anyone else having trouble rebooting/halting their SMP box using the ac kernel series since 2.4.6-ac2? I use a Tyan Tiger 230 and have been having that particular problem ans 2.4.6-ac2 was the last kernel that could successfully reboot/halt (all others since then hang at "INIT: No More Processes At This Run Level"). Also, is anyone out there using an Asus CUV4X-DLS, and if so does it work reliably, including the on-board audio, ethernet and SCSI? Thanks for any information.
