[Xenomai] Problems disabling SMI interrupts on MSI H87-G43 motherboard

[Anders Blomdell <anders.blomdell@control.lth.se>]

Hi

I have problems disabling SMI-interrupts on "MSI H87-G43 motherboard" (http://www.msi.com/product/mb/H87-G43.html)

This is what msi.c says at bootup (after attached patch is applied):

  kernel: [Xenomai] SMI workaround failed! (1830: 1 & ~1 -> 1)

and this is what lspci says:
