Actually, something is trying to read a file from the cache which isn&#39;t there. You didn&#39;t do something silly like put your cache on reiserfs did you?<div><span><br><br><div class="gmail_quote">

Hi Folks,<br>
<br>I&#39;m been attempting to setup a new server running a standard KDC (V5) and AFS (and incidentally LDAP).&nbsp; Everything configured OK (didn&#39;t get as far as creating volumes other root.afs and root.cell).&nbsp; I&#39;m seeing problems logging in as Kerberos/LDAP defined user.&nbsp; Login was fine prior to the AFS setup, post AFS setup generates a kernel &quot;crash&quot; which I&#39;m assuming is related to pam_krb5 attempting to get AFS tokens (but am not sure).&nbsp; I&#39;m seeing this with both the Fedora Core 8 RPMs from 
<a href="http://www.openafs.org" target="_blank">www.openafs.org</a> and using a locally 1.5.27 build.&nbsp; Excluding timestamps and hostname info, the 1.4.5 /var/log/messages entries are
