You're quite right, there is no option in the BIOS. To enable AHCI and SATA mode you have to manually change a flag with a DOS or freedos boot disk, a text editor and a bit of hacking. There are instructions out there, but I'm not sure for your model. Anyway, I thought that my changing the setting might have upset Linux but this bug is present regardless of the AHCI setting so it seems unlikely. -- System fails to shut down cleanly https://bugs.launchpad.net/bugs/363389 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
