Hi Jens, Andre, Robert
The box is 2.5.25-dj2 w/ 2.4-IDE and preempt running on 4-way
SMP. I have walked the entire call path manually and verified that it is
correct. Andre i do know your stance on this but please check it out
regardless, i'm willing to help in any way. For my own curiosity is that
thread flag check for TIF_NEED_RESCHED correct in this context?
Cheers,
Zwane
