Hi, I use an Intel Pentium 4 processor which can be used as 2 virtual processors when setting the SMP option during the kernel compiling (I can see 2 processors with "cat /proc/cpuinfo").
I patched the kernel with adeos in order to install xenomai. I discovered that : - when completely disabling the ACPI and setting the SMP, my system boots but I have only one processor when I look into /proc/cpuinfo - Everything goes well when I don't disable completely the ACPI. I also use a PCI framegrabber. its driver is a real time one developed under xenomai. I noticed that this driver works fine only if the PCI_MSI is set. Otherwise, I don't have any interrupts. I must use my real time driver and the 2 virtual processors. But, when I enable the ACPI, the SMP and the PCI_MSI, I have a kernel panic. My PC boots when I disable the ACPI but I loose 1 processor. I don't see what's wrong. Thanks for your help, Wael. ------------------------------------- Wael BACHTA Strasbourg I University LSIIT Laboratory, AVR group Bd S.
