Hi,

priv_emulate() may fail and while calling reflect_interruption() the isr 
register isn't provided. If the fault is the IA64_GENEX_VECTOR there are
subcodes defined (IA64_ILLOP_FAULT, IA64_PRIVOP_FAULT, ...) which can be used 
to provide the ISR.code to the domU.
A next step may provide further informations like ISR.r, ISR.w, ...
Thanks.

Dietmar
