OK, so you have an issue with the native kernel on this hardware. It is
probably worth resolving this (perhaps via a Debian bug report, unless
BIOS update helps) before going on to worry about Xen.

Presumably the version of the installer you picked up had a slightly
different kernel to the one which actually ended up installed. If you
can identify which is which then that might be useful information for
the Debian bug report.

If at this point you remove the noirq thing does it work under Xen?
