I got the same problem on my laptop: HP CQ35-111tx HD Hitatchi HTS545050B9A300 (500gb version instead of 320gb version reported by tokyohead) Intel ICH9M-E/M SATA AHCI Controller
There is no problem with the original FUJITSU MHZ2320BH G2 hard-drive. I've tested both Ubuntu 10.04, Ubuntu 10.04.x, Ubuntu 10.10, Fedora 13/14, Arch, and same problem occurred. adding a kernel option of libata.force=noncq before booting in to linux is a work around, but both the battery and hard-drive's performances will be poor. ** Changed in: linux (Ubuntu) Status: Expired => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/379831 Title: ata2 exception EMask delays/prevents booting 9.04 & 8.10 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
