I tried the one you sent to me with seperate e-mail: fx-2.2.5-A4. I applied it to 2.2.5-ac3+devfs+HZ=3D400 and it did ap= ply cleanly. Here are the results: * My benchmark now produces correct results. No strange NaN or other errors could be seen, any longer * Logging out from KDE, no problem occurs * At least two modules compiled for patched 2.2.5-ac3-fx had problem with plain 2.2.5 kernel: serial and floppy. Is FP being used inside these? Or just a matter of too small kernel structs ... ? =3D> I think the problems with your PIII patch are cured! * The benchmark results are hard to interpret. I compared plain 2.2.5-ac3 results against the ones with your patch. The 2.2.5-ac3 kernel was running for a couple of days before, whilst the patched one was freshly booted. Strange enough, the results seemed to be discouraging: they were slightly worse. After some time (compiling some KDE binaries in between), I reran the benchmark, and this time, it was slightly better than the old results. I can not conclude anything from it, but that there are some cache aliasing effects(or whatever) which do influence the benchmark more than the fxsave/fxrestore optimization. If you think it should be measurable, I can do boot into Single user mode and do a large number of tests to get a reasonable statistics. Appended is a sdiff (96 columns). left side: Plain kernel. right side: Patched kernel.=20 Thanks for looking into this problem and solving it. --=20 Dipl.Phys.
