Thanks. Any idea what to look for (I'm doing much assembly language
programming, but on microcontrollers, not on x86 - some hint what and
where to look for would be much appreciated)?
The log is attached below (sorry, rather lengthy). It's been taken
with ASMHasCpuId()'s body replaced by {return true;} for the kernel
module (don't think that makes a difference).
Thanks,
Heike
