I'd like to see the stackdump that follows the message.
go to drivers/ssb/pci.c and search this code:
573 static int ssb_pci_assert_buspower(struct ssb_bus *bus)
574 {
575 if (likely(bus->powered_up))
576 return 0;
577
578 printk(KERN_ERR PFX "FATAL ERROR: Bus powered down "
579 "while accessing PCI MMIO space\n");
580 if (bus->power_warn_count <= 10) {
581 bus->power_warn_count++;
582 dump_stack();
583 }
584
585 return -ENODEV;
586 }
Add the following line just before the "return -ENODEV;":
local_irq_disable(); while (1) cpu_relax();
Please catch the message with a digital photocamera.
