I have been using it too on Ubuntu Intrepid and Jaunty, only had a few problem on Hardy (had to backport a newer version). All machines on some kind of raid, some on ext4, but no lvm. Most machines are workstations rebooted daily, and have no separate /boot, everything is on raid. So yes it's quite stable for me. I found that even when there is a problem, it easier to quickly recover without even leaving the grub2 shell-like environment, I like the modularity of the /etc/grub.d/ templates.
I recently set grub2 up a Fedora11 machine, it's really not well integrated in the system yet, and require some manual work, but after that it just works (on ext4). Debian has done a great job integrating it. Only down sides are: _The lack of recovery live-cd that support grub2 out of the box (but a live Ubuntu/Debian does the job). _Some disk imaging tools (Clonezilla) default to (re)installing grub on the imaged disk, you have to be careful and disable it. _The "os-prober" helper package is working somewhat randomly for me, it is only supposed to auto-detect other installed systems, so no big deal. _I don't know how grub2 behaves outside of x86 machines, or with non dos disk labels. _There is no support currently for partition label in grub.cfg, I miss that, but uuid are arguably more reliable anyway. That's all for my little experience of grub2, I wouldn't go back at this point, and can't complain about stability, especially on Debian.
