RE: [Xen-ia64-devel] RE: [elilo-discuss] a patch to make elilo loadanother module

["Magenheimer, Dan (HP Labs Fort Collins)" <dan.magenheimer@xxxxxx>]

Another update...  This problem goes away when I
specify verbose=3 (or verbose=2) at the beginning
of my elilo.conf file.  With verbose off, or with
verbose=1, I get the load error.  Weird...

So on to the next step... the module (the RHEL4
initrd) gets loaded but after a few seconds (and
no console output), the system reboots.  This is
probably not unexpected as I haven't yet patched
Xen itself (awaiting latest patch from Anthony).

Time to call it a week!  Bye!
