Comment 18 for bug 26998

I am having this same problem with a fresh installation of ubuntu hardy. It was not an issue in 2.6.18-2, but is in 2.6.18-4 and 2.6.18-6 kernels. It isn't actually fresh as in it was directly installed, but was upgraded from a fresh installation of an old debian version.

I haven't tried any fixes as of yet, but I thought I should let you know you are not the only person getting this problem.
