What is going on? If I enable smp it works! Using a uniprocessor p4 with hyperthreading... huh? My best guess.. smp enables some kind of different interrupt handling, and the cpu is stuck waiting for an interrupt when probing the ata port? hmmm. Let's test. uniprocessor w/wo msi: fails uniprocessor w acpi: fails uniprocessor w msi+acpi+preempt: fails uniprocessor+apic+ioapic+msi: can't compile : drivers/built-in.o(.text+0x7022): In function `get_new_vector':: undefined reference to `interrupt uniprocessor+apic+ioapic: ok uniprocessor+apic: fails Ah-ha! So it looks like you need CONFIG_X86_UP_IOAPIC or SMP to get it working. Bug 1) xen with non apic kernel is broken Bug 2) compile error with CONFIG_PCI_MSI _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
