Thread-topic: [Xen-ia64-devel] 2 LTP math cases failed in xen0
Hi Yongkang --

Could you see if the math tests that fail are using
FPSWA (the EFI floating point software assist module)?
I think it is possible to boot Linux with FPSWA disabled.
If this also fails these math tests, it would explain
why Xen/ia64 fails these tests as Xen/ia64 does not
currently support FPSWA (or any EFI modules).
