I'm running 2.6.22-5 now, and there has been a development on this issue. Links to the LKML thread on the patch:
http://thread.gmane.org/gmane.linux.ide/18485 Basically, what it says is that it should now work as expected out of the box, if you write 0 to /sys/module/libata/parameters/spindown_compat before shutdown. This was done to support distros that were "fixed" in the mean time by doing the spindown in shutdown(8) or halt(8). Ubuntu is supposed to fix up halt(8) and shutdown(8), like it says on the accompanying web page: http://linux-ata.org/shutdown.html As for feisty, at this link there is a patch that toggles the default for stop_on_shutdown: http://permalink.gmane.org/gmane.linux.hardware.thinkpad/29772 Unfortunately it apparently tries to spin down flash devices too, which leads to nasty but innocent error messages in the kernel output. -- The SATA disk doesn't power off while shutdown https://bugs.launchpad.net/bugs/63937 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
