Modified Files: src/sys/arch/x86/x86: mpacpi.c Log Message: Configure ioapic before lapic because lapic(lapic_set_lvt()) checks the existence of ioapic. This change fixes a problem that some machines hang after attaching ehci (little after writing EHCI_USBINTR to enable interrupt). Even though cold == 1, LAPIC_LVINT0 was not set as masked. Perhaps it's the reason of the problem. This problem was observed on SuperMicro X10SLX-F, X10SDV-TLN4F and Shuttle DS57U without wm(4) driver.
