Hi All,
Looking around in the dmesg output of my Acer PC I found this messages.
I like to help the Linux community, so here is the DMI info.

I'm currently using Ubuntu 8.10 with a standard 2.6.27-7-generic kernel
on this Acer PC.
But that wasn't without some troubles. This motherboard seems to quite
tricky on the ACPI part.
For example : first try with the 2.6.27-7 kernel I got a lot of boot
errors of the following kind :
ACPI : Expecting a [Reference] package element, found type C
I don't know what it means, but the result was nothing less then a
crashing and beeping PC.
Fortunately I could select an older 2.6.24-21-generic kernel with grub
and this one booted correctly.
Then after trial and error I managed to boot with the 2.6.27-7 kernel
only after disabling the "acpi southbridge extensions" in the BIOS.
If this information can help someone or there is an explanation for the
above behaviour ... always interested to hear about it.
Or if I can help with more info ... send me a mail.
Best regards,
Wim
