Glad to help Len. BTW, what is going on here? Is there a thread where this is explained? Seems the BIOS deliberately alters the DSDT after initialisation. Do we know why? Does it do it for Win OSs? Also, I see that for kernels >= 2.6.35 the boot argument acpi=copy_dsdt is available which it sounds like it should cause the same behaviour as this patch. Is that right? In which case I can start to use that with standard distros once the appropriate kernel level is distributed for Ubuntu. Many thanks, al.
