Re: kern/56793 (Xen DOM0 device timeouts/interrupt issues (wd, mpii))

[Frank Kardel <kardel%netbsd.org@localhost>]

Better:
    - boots
    - xl list works
    - mpii works with tape/disk devices
But
    - ahd experiences two timeout during boot
    - ahd recovers later on and the tape on that device can be accessed

ahd attaches like this:

So, it looks usable/tolerable but not perfect yet
