@Marius: yes, please open a bug upstream and/or report the issue on the linux kernel mailing list, it is a good thing to do.
Also, it would be useful to know when this started to happen (which kernel version), people affected here can download kernels from http://kernel.ubuntu.com/~kernel-ppa/mainline/ and test which version started to show up this issue. So far the greater delay_use helps, but needs investigation (since as reported here 11.10, with 3.0 kernel, worked fine, even with the default delay_use=1).
