I just had a weird system freeze that I resolved using alt-sysrq-e. Here's my dmesg: https://gist.github.com/1609263
I was wondering whether it might be some kind of deadlock in the reiserfs3 code since it's mentioned so many times (and in nearly all the call traces)? Or would it look the same with any other file system?
I just want to know if ReiserFS v3 is getting so old that I should bother reformatting, just to get rid of this. If this call trace would be produced with other filesystems too, I guess it's not resolvable by changing FS.
I've been running this system for years now daily, and I never had this problem before. Not running a bleeding edge kernel either, just the standard Ubuntu 10.10 (3.0.0-14).
