Hi, Thank you for your hints.
I patched my kernel the new adeos patch (adeos-ipipe-2.6.17-i386-1.5-00.patch). and I did this tests : - SMP on and PCI_MSI on : my PC boots. I installed xenomai 2.2.0. I can see my 2 virtual processors with "cat /proc/cpuinfo" BUT, I don't have interrupts. - SMP on and PCI_MSI off : The PC boots and I see my 2 virtual processors. - SMP off and PCI_MSI on : The PC boots, I have my interrupts. It seems to me that the new patch disables the PCI_MSI when the SMP is on. The new patch doesn't seem to fix my problem. Thanks for your help.
