The entire implementation of pipes has been radically revised between 2.6.10 and 2.6.11: see, e.g., <http://lwn.net/Articles/118750/> and <http://lwn.net/Articles/119682/>. Bugs have been spotted in this area in 2.6.10: this may be another one. If you can reproduce it consistently, *please* report this to the linux-kernel list! (I don't see what you mean by `a pipe rom /proc/kmsg', though: pipes connect processes, not files. File redirections are quite different and should work unchanged in 2.6.11.) -- > ...Hires Root Beer... What we need these days is a stable, fast, anti-aliased root beer with dynamic shading.
