Feature changed by: Tim Edwards (tk83) Feature #312962, revision 6 Title: Include acpi_osi=Linux pcie_aspm=force by default for Grub boot parameters openSUSE Distribution: Unconfirmed Priority Requester: Important Requested by: Roger Luedecke (shadowolf7) Partner organization: openSUSE.org Description: acpi_osi=Linux identifies the OS to the BIOS helping fix power and other issues. pcie_aspm=force fixes power regression issue shown here; http://www.phoronix.com/scan.php?page=article&item=linux_2638_aspm&num=1 Discussion: #1: Bruno Friedmann (bruno_friedmann) (2011-11-12 20:59:37) As GHK answered by email on the mailinglist and you didn't report here the result : would you like to kill 80% of working computers ? Just to save some type of Acer buggy bios. I'm not for. please remove that feature. or at least be kind enough to post the result of the discussion! #2: Jon Nelson (jnelson-suse) (2011-11-12 23:37:57) (reply to #1) Correct. Forcing these params is /wrong/ for the majority of computers out there. Besides, it appears as though a fix for this has just appeared in the last few days. #3: Joseph Mitzen (duncreg) (2011-11-13 01:57:10) (reply to #2) Phoronix's articles lend the impression that the vast majority of boards reporting no support do actually support the feature, in contrast to the claim here to the contrary. They even have a list of several DOZEN motherboards that incorrectly report not supporting ASPM when they do. I don't know where the first commenter's idea this is simply an Acer problem comes from. You are correct that patch(es) have just appeared that seem able to fix this. Hopefully, they'll be backported to OpenSUSE 12.1. + #4: Tim Edwards (tk83) (2011-11-14 09:51:40) + The mailing list thread discussing it is here: + http://lists.opensuse.org/opensuse-factory/2011-11/msg00395.html + In short it's not a good idea, and Phoronix is not a reliable source of + information compared to the kernel developers. -- openSUSE Feature: https://features.opensuse.org/312962
