Well, this unfortunately does _not_ test the F00F debugging code :-(
Could you (and evrybody who has time to do it) please use TEST WISE the below patch _on top_ of 2.0.32-pre6. ^^^^^^^^^ This will fake a buggy Pentium even on a PPro.
Though you can't test if the F00F bug is catched, the machine does all the rest of what a Pentium machine would do (e.g. will show if there are bugs in the code itself). Please test it then with all kind of debuggers you have. ^^^^^^^^^^^^^^^^^^^^^ BTW: the pre-patch is on ftp://ftp.kernel.org/pub/linux/kernel/testing/pre-patch-2.0.32-6.gz Thank you, Hans <lermen@fgan.de>
