Hello,

fcp doesn't seem to work in xen when copying large files.  It freezes
the network (can't ping) but I can use the xen console just fine at
that time.  After a while the network unfreezes, but I get this error:

cpu% fcp /n/sources/plan9/386/9pcf /tmp

so, pread(2) is failing.  Also, /n/sources is not accessable
afterwards.  Bad network driver?

TIA,
fhs
