Xen devel - Aug 2006 - Spliting IRQ between VM, RTC timer problem, IRQ 8 ...

Hello,

I''ve just found post on the user list about Asterisk / Zaptel
ztdummy problem

Ztdummy use  rtc.ko  module and IRQ 8  ...
When I start the VM or If I done a modprobe of ztdummy,  the kernel tell 
me that resource is not free ...

rtc: IRQ 8 is not free.

Does it exists a solution with  Xen 3.0.2 ?
To share this IRQ or give and access to IRQ 8 from dom0 ?
