odd problem with XFS & NFS (locking up system)

[Dave Alden <alden@math.ohio-state.edu>]

Hi,
  I'm having an odd problem with the latest CVS (as of 03/11/02 11:00am EST).
I've compiled and installed the kernel, but whenever I attempt to copy a
file over NFS, the server locks up.  Any windows I have open on the server
stop responding.  I tried to a <ctrl>-A, followed by a bt and I got:

Entering kdb (current=0xc045c000, pid 0) due to Keyboard Entry
kdb> bt
    EBP       EIP         Function(args)
0xc01053b0 0xc01053d3 default_idle+0x23
                               kernel .text 0xc0100000 0xc01053b0 0xc01053e0
           0xc0105452 cpu_idle+0x52
                               kernel .text 0xc0100000 0xc0105400 0xc0105470

Help?

...thnx,

ps  This problem doesn't seem to occur if I copy a file from an EXT3
    partition over NFS, only XFS.  It also doesn't happen if I reboot
    to the original XFS kernel (2.4.9-13SGI_XFS_1.0.2).
