What I-pipe patch version are you using? Could you try with CONFIG_PCI_MSI disabled? There has been other reports on MSI issues recently, maybe yours belong to the same group. Thanks, Jan PS: Unrelated to the problem but maybe still interesting: If you plan to use Adeos/I-pipe as a real-time enabler (e.g. with Xenomai), you should switch off CONFIG_ACPI_PROCESSOR, CONFIG_CPU_FREQ, and CONFIG_APM. Recent Xenomai versions should warn you about this fact as well.
