I have updated to 2.6.24-5-generic kernel and the error have changed from "ata1.00: failed to set xfermode (err_mask=0x40)" to "ata3.00: failed to read native max address (err_mask=0x4)"
I think it's a incompatibility with the motherboard "Abit IB9". I don't know if it would be better to post in a new bug report or here, sorry if I don't do it correctly. ** Attachment added: "dmesg" http://launchpadlibrarian.net/11589280/dmesg -- Unable to boot 7.10 on abit ib9 due to ata xfermode https://bugs.launchpad.net/bugs/172300 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
