Ok, this confirms my suspicion that it is shared-irq related. Also, we already verified that switching to libata does fix the issue for you so you are good to go. Considering the DEPRECATED status of ide, I have a very little incentive in hunting this thing further down, so let's leave it at that. I'll send the first fix to Dave since it is still needed and add a note to bugzilla for further reference. Jonas, big thanks for your hard work with testing patches and ideas. I really appreciate it! :) -- Regards/Gruss, Boris.
