[OpenAFS] Re: Solaris 10 crashing - BAD TRAP ... NULL pointer dereference

[Jeff Blaine]

For the record, the *incorrect* official documentation section
about loading the kernel module under Solaris:

BEGIN QUOTE
If the machine is running Solaris 2.6 or the 32-bit version of Solaris 
7, its kernel supports NFS server functionality, and the nfsd process is 
running:


    # cp -p modload/libafs.o /kernel/fs/afs

If the machine is running Solaris 2.6 or the 32-bit version of Solaris 
7, and its kernel does not support NFS server functionality or the nfsd 
process is not running:


    # cp -p modload/libafs.nonfs.o /kernel/fs/afs

If the machine is running the 64-bit version of Solaris 7, its kernel 
supports NFS server functionality, and the nfsd process is running:


    # cp -p modload/libafs64.o /kernel/fs/sparcv9/afs

If the machine is running the 64-bit version of Solaris 7, and its 
kernel does not support NFS server functionality or the nfsd process is 
not running:


    # cp -p modload/libafs64.nonfs.o /kernel/fs/sparcv9/afs
