Hi!
On 64-bit machine with 4GB ram (8core from amd), iommu breaks USB after swsusp. iommu=soft fixes that issue.
I guess iommu handling in arch/x86/kernel/ should have some suspend/resume support, as it manipulates hardware registers...? Pavel -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html
