Re: Broken ACPI in kernels > 2.5.69, blows up upon boot

[Len Brown <len.brown@intel.com>]

Hi Paulo,

This looks different from other failures I've seen in bugzilla.  Is it
possible for you to try the latest kernel (2.4 or 2.6 will do -- they
have the same ACPI code) and drop the info below into bugzilla?

thanks,
-Len
