So, I have a little netbooting box, and for a long time, it Just Worked.
A while back (maybe September?) I started having trouble with it. Sometimes
it can netboot. Sometimes it can't. When it can't, the symptom is
mount_nfs: bad MNT RPC: RPC: Timed out
What's weird is, sometimes just trying again makes it work.
I've tried this with and without the TCP/IP flag on mounts; it doesn't seem
to matter. Same exact hardware every time.
The kernel for this box defines
options NFS_RSIZE=8192
options NFS_WSIZE=8192
but this was only necessary (as I understand it) with UDP; it shouldn't
matter with TCP mounts, but they have the same problem.
Once a filesystem is mounted, it works beautifully, but mounting appears to
work about one time in three. If a given filesystem doesn't mount on the
first try, no force on earth can make it mount later.
There must be *something* here I don't know about.
