I have a machine which i have (oct 25) cvsup and moved to RELENG_5. It was previously running 5.1. The machine does not use vinum. I am using 'amd' automounter. When a certain host becomes unavailable (that host is using=20 nfsv2), automounter times it out. During the umount (sometimes?=20 always? not sure), i get: "unmount: dangling vnode" panic. I have a vmcore from it, and a kernel.debug. I'm a little confused on gdb, there is no -k switch anymore? I'm very familiar with 4.x, less so with 5.x, how does one do kernel debugging with gdb? The handbook still says -k=20 (http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/ker= neldebug-gdb.html) Has anyone seen this? Is there a workaround?
