Comment 122 for bug 445852

We have many reports of the libatasmart code causing stalls, HSM Violations and even death of SSDs. Particularly SuperTalent ones, but also those found in my netbooks.

# sleep 120; logger devkit-disks-probe-ata-smart; /lib/udev/devkit-disks-probe-ata-smart /dev/sda; sleep 120; logger done

And I get this in syslog (repeatably):

The problem has also been confirmed in Fedora 12.
