With 2.6.22, did you notice any functional difference with "acpi_osi=!Linux"?

(or since the default changed at 2.6.23, with 2.6.23 or later
do you notice any difference with "acpi_osi=Linux"?)

Please send me the output from acpidump.
If you don't have acpidump, you can get it from pmtools here:
http://www.lesswatts.org/projects/acpi/utilities.php

thanks,

with grub, you should be able to select a menu line with the up/down arrows and 'e' to edit the selected line
adn select the kernel line of that entry and type 'e' to edit that and then type in the modification to the cmdline, RETURN
and 'b' for boot.

This is safer than editing menu.lst, for if the option doesn't work you haven't made it default. And if you do edit that file, it is probably a better idea to copy the entry to the end of file and edit it there rather than editing your default boot cmdline.

i don't know why a modification to your grub boot.conf might not take effect. maybe since it is before ### END DEBIAN AUTOMAGIC KERNELS LIST there is something special about it... you could find out by copying it to after that line and editing there...

editing menu.lst to add this parameter works on my fedora box.... maybe debian is doing something funny like not using that file and instead using a different copy of it?

Thanks for the acpidump -- it is similar to other Acer models in that it will disable the Windows-compatible path through the BIOS with no apparent upside for Linux.

                    If (\_OSI ("Windows 2006"))
                    {
                        Store (0x40, ^OSTB)
                        Store (0x40, ^TPOS)
                    }

                    If (\_OSI ("Linux"))
                    {
                        Store (0x01, LINX)
                        Store (0x80, ^OSTB)
                        Store (0x80, ^TPOS)
                    }

In the case of the Acer Aspire 5050, LINX and OSTP are NOPs however TPOS is compared to 0x40 in the SATA code. Safer to keep OSI(Linux) disabled on this box unless we find ourselves incompatible with the Vista SATA ACPI hooks.

This means that your cmdline override worked.
It also means that OSI(Linux) was enabled, which means you were running 2.6.22.

this also means that you are running 2.6.22, which had OSI(Linux) enabled by default and wasn't smart enough to change the line above when there was a cmdline override.

2.6.23 is just as dumb, but with the opposite polarity:-)

The patch for 2.6.24 will be a little more clever, and I'll probably send it to 2.6.23.stable as well...

thanks,
-Len
