Re: Testing requested for the next version of GNU Mach

I haven't been able to boot gnumach with upstream GRUB since this X15
code was imported.  It does boot successfully with QEMU's multiboot
arguments, and it seems fine when it's running.

When booting the latest gnumach (689810) with GRUB (both old versions
and today's beta3 release) built for the i386-pc platform, the
following is displayed for a fraction of a second before the system

The same GRUB has no problem booting older gnumach (bee3f0) or Linux.
Are you aware of any patches required by GRUB to boot the X15
multiboot/biosmem bits?
