Hi, do you know how, in the case of volountary preemption and threaded irq handlers, the irq's used by X11 are handled? i removed the nvidia module from my kernelvand rebooted to have it untainted, but of course the X11 nv module does neither report to /proc/interrupts nor /proc/irq. SInce it is on another bus [agp] i suppose this is no problem but i always wondered about the interplay of the kernel an X. It looks to me like an area which might still have some surprises..
