Right, good point. I'll boot the machine nosmp and try to reproduce the oops over the weekend.

trouble is, I have no idea whether the bug is present in earlier 2.4 kernels as well without me noticing, or if it's a relatively new thing (Sure I could check, but it's not like I can reproduce the oops in under an hour or so of trying: that's what I meant by "more-or-less-deterministically" :D).
