RE: [Xen-ia64-devel] RFC: Switch to xlilo now? Or post-3.0?

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

Thank you very much for your complete instructions.

I am now able to get further but domain0 still crashes.  Just after

        Freeing unused kernel memory...
        Warning: unable to open an initial console...
        cdrom: open failed

I get a very long string of errors

        nbd0: Request when not-ready
        end_request: I/O error, dev nbd0, sector 0
        Buffer I/O error on device nbd0, logical block 0 [ and 1]

this repeats for nbd1-nbd15.  After which I get:

        kjournald starting. Commit interval 5 seconds
        EXT3-fs: mounted filessystem with ordered data mode

But then (from Xen):

        handle_op: can't handle privop at 0xa000000000010670 (op=0) slot 0 
(type=5)

(note, NOT 0xa000000100010670)

and

        udevstart[1047]: General Exception: IA-64 Privileged Operation fault 16 
[1]
        Modules linked in:

and then a a long string of kernel core dumps, the first of which
is comm=udevstart.

One difference in my process is that mkinitrd unless I
add the following arguments: "--builtin mptbase --builtin mptscsih"
(These are the Fusion drivers necessary to boot the HP box.)

So I am still not able to boot RHEL4 with Xen but I guess this is progress :-)
