Off-hand I don't have any idea what could be wrong and what can be done. I doubt this is caused by iwm itself since iwm works well in many other machines. More likely there is some problem in the layers iwm relies on. Perhaps something is going wrong with PCI power management. But that is just an uninformed guess of mine and I am not a PCI expert. As far as I understand the reason for having to "acquire" the device in the driver is that the chip may decide to go to sleep to save power and needs to be woken up before it can be accessed again. This wake-up seems to be randomly failing in your case.
