No issues with this one:- 00:1f.2 SATA controller [0106]: Intel Corporation 82801HBM/HEM (ICH8M/ICH8M-E) SATA AHCI Controller [8086:2829] (rev 03) (prog-if 01 [AHCI 1.0]) with a WDC_WD5000BEVT-80A0RT0 disk. However, the controller appears as a SATA-IDE controller (8086:2828) that uses the piix driver by default, and you need a custom kernel (AFAICT) to quirk the 8086:2828 controller into AHCI mode whereby it turns into 8086:2829, and uses the ahci driver, allowing for the SATA link power management. -- Kind regards, Loong Jin -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/539467 Title: SATA link power management causes disk errors and corruption -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
