Longhaul - Revert ACPI C3 on Longhaul ver. 2
PATCH 1/1 Longhaul - Revert ACPI C3 on Longhaul ver. 2
Support for Longhaul ver. 2 broke driver for VIA C3 Eden 600MHz with Samuel 2 core. Processor is not able to switch frequency anymore. I don't know much about this issue at the moment, but until (if ever) I will know why, this part should be reversed. I hope it isn't to late to include it in 2.6.21.
