I just ran this test against 2.6.24-rc7, and it worked fine for
me. There may be fixes that went in over the last few months to
mainline that could impact this particular use case. If I can find the
time, I may make another backport release, but for now, I recommend
just trying the mainline 2.6.24 kernel (the current -rc release is
pretty stable at this point, and I expect the official 2.6.24 kernel
to come out in the near future).
Thanks,
Mike
