    SubjectNFS oops with 2.3.99-pre3

    While copying a file to an NFS filesystem, cp got stuck and I later
    found an oops on the console.

    These are mounted:

    pc-sw8:(pid282) on /net type auto (intr,rw,port=1023,timeo=8,retrans=110,indirect,map=/etc/amd/
    inxs4:/export/home on /amd/inxs4/root/export/home type nfs (rw)

    This seems to be the hung process. There is no PID 6569, and there
    were no messages about PID 6571. Anyway, cp is stuck in __down().

    000 D 6571 1 0.0 39 down 107ab0 cp

    Running "uname -a" on the server called inxs4 reports:

    SunOS inxs4 5.6 Generic_105181-11 sun4u sparc

    I'm using an "amd" that comes from Debian, and it reports:

    Unofficial patch level 102.
    amd of 1992/05/31 16:53:21 bsd44-beta #0: Wed Aug 9 14:16:02 PDT 2000

    Here is everything I could get off the console. Since gpm is still
    working, this ought to be accurate.

    These didn't map to anything. (many are stack addresses)
