Maybe a per-cpu variable is the wrong way to go about it. I'm trying to get a better understanding of why, even quite simple, structs get corrupted when accessed by kernel threads. The compiler may be at fault, but is it possible that there is something else going on, which is specific to alpha and we're seeing more of this on more recent kernels which makes better use of threads? /Magnus
