AO_fetch_and_sub1_write, AO_fetch_and_add_write, etc are in both bugs. (This is to be expected, since the most probable cause of atomic-ops issues are problems with definition chaining.) Well, can be. As I see, the original bug was fixed in Debian as well[1]. > 2) I notice that this is in the compile output: "Kernel: Linux 2.6.31-rc9 armel (armv5tel)" > Does that mean it's building on an arm v5 machine? > I wonder if maybe there's an issue there -- my knowledge of the ARM architecture is extremely limited (basically just tracking issues like this down) but from what I've read there were some changes which could account for a bug like this. Notably, atomic-ops for arm depends on the "__arm__" preprocessor variable being defined, which I'd expect to be defined for any version but maybe isn't. I have to run and will have time only in the afternoon (CET). Until then I can give you only pointers. The email list of ARM porters: http://lists.debian.org/debian-arm/ . It's not moderated, so you can post there. IRC can be faster, you can find #debian-arm on irc.debian.org .
