Re: [ACPI] No handler for Region [ERAM] on Gateway M350?

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Check the archives of this list for the threads titled:

  /proc/battery empty on Gateway 400VTX
  acpi on gateway 200x
  acpi on new gateway laptops
  Gateway 200x - trouble supplying ECDT table
  ACPI/ECDT on gateway 200x notebook

As well as this bug entry:
  http://bugzilla.kernel.org/show_bug.cgi?id=1744

In short:
  1) Apply the latest acpi patches

  2) Make sure your DSDT is correct as per
     http://acpi.sourceforge.net/dsdt/index.php

  3) Apply the patch listed in the bugzilla entry

I believe the patches were for 2.4.x branch. I'm assuming once a suitable
fix/workaround is determined this stuff will make it into the standard
acpi patch sets and eventually into the mainstream kernels. Not exactly an
easy solution, but it does appear to work for those that have tried it.
