Might be some other weirdness, as I did not try to reproduce it more than twice. And then something else - gnome did not want to start due to missing icons. They are there however, and rebooting to old kernel without libata worked fine (same kernel, just do not have the patch applied or the normal ata driver disabled). I will give it a go some more. Currently I am having some issues with getting latest cvs glibc & nptl to play nice, so I will not take it too serious for now. If anything obvious might cause it and you want me to test, ask. Otherwise I will give it a good run in the next few weeks and get a more complete report.
