There is a known issue in the adeos patch, that the I-pipe patch does not have. This was discussed several time on RTAI mailing list. You should try booting with the pci=routeirq option or disable the IO-APIC support. See : https://mail.rtai.org/pipermail/rtai/2005-April/010921.html -- Gilles Chanteperdrix.
