Description Benjamin Reed 2006-09-01 19:03:15 UTC 
Description of problem:
I am unable to view/edit a large number of files over an autofs-mounted NFS
directory.

Version-Release number of selected component (if applicable):

Here's all of the possibly-relevant stuff:
  autofs-5.0.1-0.rc2.1
  kernel-2.6.17-1.2608.fc6
  nfs-utils-lib-1.0.8-7.2
  nfs-utils-1.0.9-5.fc6
  portmap-4.0-65.2.2.1

How reproducible: every time

Steps to Reproduce:
1. boot
2. cd to a directory that is NFS-mounted
3. cat CVS/Root
  
Actual results:
$ cat CVS/Root
cat: CVS/Root: Input/output error

Expected results:
the contents of the file  ;)

Additional info:
dmesg has a large stack trace from the kernel; attaching as "dmesg.out.gz"

Comment 2 Benjamin Reed 2006-09-01 19:23:47 UTC 
I just confirmed that reverting to kernel-2.6.17-1.2157_FC5 fixes it, so it must
be a kernel issue specifically (although going by the dmesg output, that was
pretty clearly the case anyways :)
