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 ------------------------------------------------------------------------------ Andrew Gallatin, Sr Systems Programmer http://www.cs.duke.edu/~gallatin Duke University Email: gallatin@cs.duke.edu Department of Computer Science Phone: (919) 660-6590 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
