Please advise. Thanks.
Comment 1 Andrew Morton 2007-08-08 23:44:33 UTC 
- This is against 2.6.9, which we haven't worked on for years - please
  retest kernel.org's 2.6.22 or contact your vendor

- The kernel is tainted by proprietarty modules

- This is a core x86 problem, not an NFS problem.

Thanks for reporting it, but there isn't anything the kernel.org team
will be able to do about this, so I'll close the report.
