Comment 12 for bug 262437

@Marques,

your problem might be related to a bug found in the hpet code. That should actually work with the kernel at http://people.ubuntu.com/~smb/bug254668/linux-image-2.6.27-3-generic_2.6.27-3.3smb2_i386.deb

There were also other problems in related places and I am currently building a kernel with all of them in. But maybe you have the time to check whether this single patch already helps in your case.
