Ok, I've just seen it again. Here's the call that's failing:

lstat("../lib/", 0xbffffb98) = -1 EIO (Input/output error)

It seems that sometimes I can provoke it 4 or more times in a row, other
times no matter how hard I try, I can't. "4 times in a row" here means
umounting and then remounting the export on the assabet.

As I mentioned in my last (private) mail, the setup was slightly different
from my first description.

flint (nfs client) is responsible for writing these files onto the NFS server
(raistlin), and the programs are run on assabet (nfs client).

  kernel 2.2.18-cdhs (raid)

  mount indicates:
  raistlin:/usr/src on /net/raistlin/src type nfs (rw,rsize=4096,wsize=4096,addr=

  kernel 2.4.16
  universal NFS server 2.2beta48

  raistlin's exports file looks similar to the following:

  /usr/src flint(rw,no_root_squash)
  /usr/src/v2.5 assabet(ro)

  kernel 2.5.1-pre10

  mount indicates:
  raistlin:/usr/src/v2.5 on /usr/src/v2.5 type nfs (ro,nolock,addr=
