Public bug reported:

Binary package hint: kernel-image-2.6.17-9-generic-di

Having gone through 2.6.17-{8,9} I am finding that on an NFS client of
my Edgy NFS server (exported home dirs for automount by clients) I am
getting Permission denied errors for just some files:

$ id
uid=1001(brian) gid=1001(brian) groups=3(sys),101(users),1001(brian)
$ ls -ld .ssh{,/{known_hosts,authorized_keys}}
drwx------  2 brian brian   4096 Jul  4 13:48 .ssh/
-rw-r--r--  1 brian brian   1004 Dec 29  2001 .ssh/authorized_keys
-rw-r--r--  1 brian brian 130456 Aug 10 15:19 .ssh/known_hosts
$ wc -l .ssh/{known_hosts,authorized_keys}
 462 .ssh/known_hosts
wc: .ssh/authorized_keys: Permission denied
 462 total

As you can see, there is no reason why trying to read
.ssh/authorized_keys should return EPERM.  Additionally, a subsequent
attempt just a few seconds later:

$ wc -l .ssh/{known_hosts,authorized_keys}
wc: .ssh/known_hosts: Permission denied
wc: .ssh/authorized_keys: Permission denied
0 total

And again only a minute or two later:
$ wc -l .ssh/{known_hosts,authorized_keys}
   462 .ssh/known_hosts
     0 .ssh/authorized_keys
   462 total

And the count from .ssh/authorized_keys is obviously wrong.

This was all working fine in the 2.6.17-6 kernel.  I only just in the
last day revved up through -8 and now -9 and these problems started.
