[Bug 445852] Re: devkit-disks-probe-ata-smart causes HSM Violations on SSD, and potential hardware death

[J-Pierre Rouits]

Surprisingly, the fix from a few days ago also fixed the random freezing at boot time that I experienced from the time I installed Karmic. I have no SSD but an ATA disk. However, the CDROM drive continues to be probed randomly giving an HSM violation. See the following kernel log:
