Author: yongari Date: Mon Nov 8 20:14:38 2010 New Revision: 215003 URL: http://svn.freebsd.org/changeset/base/215003 Log: MFC r214542: Don't bother to enable ASPM L1 to save more power. Even though I am not able to trigger the issue with sample boards, some users seems to suffer from freeze/lockup when system is booted without UTP cable plugged in. I'm not sure whether this is BIOS issue or controller bug. This change fixes AR8132 lockup issue seen on EEE PC.
