Sorry, I just realized that I rejected your preemption explanation without explaining why: 1 - In my "Text Section" lock code, which is the original place where I triggered the problem, I take a spinlock around these operations, which disables preemption. 2 - My sample module plays alone in its own data structures: there is only one thread accessing the data at a given time (because I do only one file open at a given time, which I control).
