OK, will do. I'm mainly waiting for the next rev of the ata driver
The volume this box serves up is a ccd stripe of 4 18GB ide disks
attached to multiple Promise controllers.

OK, thanks. Good to know.
Speaking of NFS changes, there was talk at one time about turning the
nfsm macros into functions. Is this going to happen?
I ask because I've seen occasional unaligned access panics on
FreeBSD/alpha in the client side code. I've only seen them on a
really lossy link (basically a misconfigured duplex on a 100Mb link).
They tend to be in nfs_request (nfs/nfs_socket.c:110) or nfs_readrpc
(nfs/nfs_vnops.c:1093). These are both calls to nfs macros that would
be a lot easier to debug if they weren't macros ;-)
Thanks,
Drew
