Derek was able to trace down the reason for the fault witn kgdb. I'd guess it likely has something to do with these recent changes to osi_vnodeops.c. I'll take a closer look, but I'm not really familiar with what's going on in the code here.

There were a bunch of changes for revalidate_dnode. -- Nathan ------------------------------------------------------------ Nathan Neulinger EMail: [EMAIL PROTECTED] University of Missouri - Rolla Phone: (573) 341-4841 Computing Services Fax: (573) 341-4216 > -----Original Message----- > From: Derek Atkins [mailto:[EMAIL PROTECTED]] > Sent: Thursday, March 14, 2002 12:23 PM > To: Neulinger, Nathan > Subject: Re: Have you had a succesful build+use with current openafs? > > > Yep. kgdb.sf.net.
