<span class="quote">> So... the mystery is where does this 0x40 method come from.</span >
Can we add a bit of debug code somewhere, to detect that specific value when it
enters the ring, and emit useful information like a kernel stack trace? I don't
mind recompiling my kernel to test stuff, and it seems chances of reproducing
this are surprisingly high, but I haven't written any kernel code myself so
far.</pre>
