Re: [Xen-ia64-devel] [PATCH 0/7] vti save-restore

[Isaku Yamahata <yamahata@xxxxxxxxxxxxx>]

Hi Alex.
Thank you for the register dump. Otherwise it had been very hard
to track it down without the info.

The culprit is the patch, 1/7 fix ia64_leave_hypervisor.
Although I haven't figured out why the patch causes hang yet,
just omitting it is okay for now because it isn't directly related
to HVM domain save/restore,

I updated and attached the patches.
I can boot linux with GFW of
  - the precompiled binary added by c/s 35:ad52e9f19cbc
  - c/s 32 with unaligned patch by Kouya.
    (Withouth Kouya's patch, it results in domain panic.)
  - efi-vfirmware-cset28.bin you offered

thanks.
