I was quite surprised actually that the machine did not go into an infinite loop of log writing. Anyway, the logs I obtained are huge and finding relevant information to post on the list proved to be quite a difficult task. Anyway, thanks for your tips, I will try the patch on a 2.6.10 and a 2.6.11-rc3, and inform you about what's going on. Expect an answer maybe tomorrow, maybe by the week-end.
