Comment 29 for bug 595138

Reading again the first posts from this thread, seems I made a mistake posting my comment here.

Maxim Tikhonov could get udev to trigger /lib/udev/hdparm manually, but not during boot sequence.

My problem was actually that of bug #222458 : a bug in hdparm-functions that prevented it to "recognize" hard drives described by a symlink (e.g. /dev/disk/by-id/... ) instead of their device file (/dev/sd*) in /etc/hdparm.conf.

Thanks Gerry for pointing me to the solution.
This bug has indeed been fixed in 13.04 (hdparm_9.43), but not back-ported to 12.10 so I modified hdparm-functions manually and it works :-)

BTW, I've just realized that :
    - bug #222458 is dating back from April 2008
    - the patch you sent the link to, is dating back from June 2011
    - it took 2 more years for the fix to be released with 13.04

That makes a total of 5 years for this bug to be fixed !! :-/
