Umm, it's really late to merge things for 2.6.19. How severe is this bug? Why has it not been found until now if it causing crashes? - R.

We found this bug actually through a code review by random. Since (un)fortunately the queue pages were layouted in order, we've not seen it earlier. It's certainly a bug and can cause kernel panic if above observation is not met, probably in stress situation of system. That means the "former" code accesses next page that it has not allocated.
