Comment 3 for bug 567182

The new hdparm package doesn't fix all my problems. I still get errors late at boot just before gnome start appearing.
And also it is impossible to update the acpi-support package.

However, booting with the nohdparm argument did the trick. I have been able to update the acpi-support with now problems and the resets late at boot are gone.
Thank you for mentioning the nohdparm argument. I've been looking for a solution for 5 months.
With karmic i also had these kind of problems.

What are the consequences of booting with nohdparm?
