Comment 4 for bug 30223

That's a seperate issue altogether. We can't guarantee that booting with this option will work now or in the future. It's a workaround.

What I'd really like is to resolve your other issues instead. The ones that occur without this option.

Please file bug report(s) for those issues.

Note, the 2.6.15-15 kernel that will be available in a few days has a huge acpi update. Maybe it will resolve some of your issues.
