Re: [PATCH 0/2] Fix wide ioport access cracking

[Gerhard Wiesinger <lists@wiesinger.com>]

Hello Avi,

Thank for the fast fix. Unfortunatly it still doesn't work (but LSI BIOS 
is initialized correctly).

I'm getting at boot time:
qemu-system-x86_64: /qemu-kvm-test/memory.c:1168: 
memory_region_del_subregion: Assertion `subregion->parent == mr' failed.

Thnx.

Ciao,
Gerhard
