Well, there is one problem I vaguely remember that I don't think has been addressed, I think it was one of those lets-put-it-off-till-v4 things. It was the fact that there are a limited number of inodes (or keys, or whatever you call a unique file), and no way of knowing how many you have left until your FS will suddenly, one day refuse to create another file. (For comparison, ext3 seems to support not only telling you how many inodes you have left, but tuning that on the fly.) But, I haven't run into that, and the only problem I've had lately has been Reiser4 losing data, and crashing occasionally. I switched most of my data off of Reiser4 and onto XFS for that reason. I've also been using ext3 in some places, and Reiser3 in others (one place in particular where space is limited, but I will have tons of small files). I later learned that XFS does out-of-order writes by default, making me think I should give up and invest in UPS hardware. But, switching away from Reiser4 means I no longer see random files (including stuff in, for example, /sbin, that I hadn't touched in months) go up in smoke. Ordinarily I like to help debug things, but not at the risk of my data. Maybe I'll try again later, and see if I can reproduce it in a VM or somewhere safe... I do still follow the list, though, in case something interesting happens. It was fun while it lasted!
