That doesn't really mean much. My U2 ran for 45 days on 2.6.12 before locking up 
solid. It was killed by a nightly rsync of the Gentoo portage tree. It had done 
the same sync 44 times previously, but that time took it out. With 2.6.17, it 
hard locked the first time I synced the tree on a new install, but that was a 
full sync instead of just a small subset like with 2.6.12.
