Oh sorry, I did that wrong. I have tried with dbg = = 0 and #define AUDIT, and it is indeed far less verbose. However I experienced the same problem as with DEBUG, ie when the guest is running slower (in that case due to AUDIT), the problem get away and the guest is running correctly, but very slowly. I guess it will be difficult to debug such a thing, so I think I will have to wait until another way to trigger the bug is found. Anyway, thanks for your help. Bye, Aurelien -- .''`.
