Hi, I'm just working on IRQ routing using ACPI. I put the code to readout the routing table and reassign the irq's in arch_int_init_post_vm. The problem is that there is crash when I try to get the ACPI module: PANIC: page fault, but interrupts were disabled. touching address 0x0000000c from eip 0x80058c22 Any quick ideas what is missing at this point to load the ACPI module? thanks, Clemens
