However I am wondering - why are you using '/mapbs' ? What did it
help? (The combination of 'efi=no-rs' means you are in effect not
using _any_ EFI operations - so doing /mapbs is not needed).
I used /mapbs because it was suggested in #irc by a dev (IIUC) @citrix
to do exactly that in response to the crash.
What it helped is that it cured the crash.
I switched to using efi=no-rs _instead_ of /mapbs because it was
recommended by a Xen dev that I do so, having called into question the
robustness of /mapbs as a fix, calling it 'quite ugly'.
Using just efi=no-rs also cures the crash, with the additional removal
of a non-fatal acpi error.
I'm now using more than just /mapbs -- specifically, adding efi=no-rs
and reboot=acpi -- for, admittedly, no good reason other than you'd
suggested I do so, above.
I'll see what I can manage with the patch you've provided. First, tho,
I need to reread all the various commentary, as I've completely lost
track of what the functions and benefits of any one option, or combo
thereof, are ...
