Re: [Xen-devel] fyi, Xen's EFI workarounds (/mapbs & efi=no-rs) on SuperMicro hardware; fixes solve 1/2 problems & SM responds that can't/won't fix their firmware

Can you try 'reboot=acpi' ?

...
I.e., what combination of

/mapbs
efi=no-rs
reboot=acpi

All? It should be on the Xen command line.

with /mapbs on the EFI exec line,

        grep mapbs /boot/grub2/grub.cfg
chainloader $cmdpath/xen-4.6.0_04-398.efi xen-4.6.0_04-398.efi config.1 /mapbs

and on the Xen Cmd Line,

        grep efi= /boot/efi/EFI/opensuse/xen-4.6.0_04-398.cfg
options= dom0_mem=3072M,max:3072M ... loglvl=all guest_loglvl=all efi=no-rs reboot=acpi

not clear to me what effect, if any, the addition of 'reboot=acpi' and '/mapbs' has, relative to just 'efi=no-rs' has.

In detail,
