Is this a known issue which is resolved in > later kernel versions? Can you try yourself whether the kernel oops still occurs with a more recent kernel, e.g. 2.6.24.4 ? If you can reproduce this with a recent kernel, the change is much higher that someone will look at this issue than for kernel 2.6.14.7. Bart.
