That's why it's marked experimental, and unlike the rest of the "experimental" drivers, we aren't kidding. It's just *one* issue that has generated all the disk corruption reports. Putting the processor into the C3 power state, in combination with bus mastering. This is disabled in the most recent release. I'd love to fix this one, but if it were easy, it'd be fixed by now. Maybe you can shed some light - if you're willing, let me know and I'll describe the problem in greater detail. > I've been discussing with a few folk about doing an > alternative mini acpi > subset so that Linux can be booted on most 'ACPI only' > hardware without > using all the ACPI junk Could these discussions be opened up to a wider readership? Perhaps you could use linux-pm-devel@sourceforge.net, or acpi@phobos.fachschaften.tu-muenchen.de? Regards -- Andy
