I know, you have right! I get the same answer from linux-raid list. But now I think I must ask you: Are you sure? I use continually the debug-kernel, and now I get another strange bug! Before your patch, I have used this system, with 2.6.13-rc3, and it was "stable", except the assertion (cnt <= tp->packets_out) problem. The only change on the system is the kernel upgrade from rc3 to rc6, and your two patch. (fix+debug patch) Originally I gets this assertion about 1-2 times / day with rc3. Before your patch, I try one time the orig rc6, and the assertion comes 4 hours later. But with your patch it looks like now I gets these strange messages INSTEAD of kernel assertion... Naturally I am not sure! It just looks like.... Additionally I will send these messages to GNBD-list too. (If I ever found that list...)
