It appears I was being hasty in blaming 3.0.4 for introducing the bug. I tested the following configurations:

Xen 3.0.3_0: works with 3.0.3 kernel ( and 3.0.4 kernel ( Fails with -unstable kernel (2.6.18). Xen 3.0.4_1: works with 3.0.3 and 3.0.4 kernels. Fails with -unstable kernel. Xen unstable: works with 3.0.3 and 3.0.4 kernels. Fails with - unstable kernel.

So, 3.0.3 and 3.0.4 work as distributed, but the latest -unstable is broken.

The reason I attributed the blame to 3.0.4 was because I had seen the same bug in -unstable during the 3.0.3-3.0.4 interregnum; however, this bug seems to have been fixed for the 3.0.4 release, and re- emerged since with the transition to 2.6.18.

Is there a pattern for how these bugs have been fixed in the past, so that I could go about trying to make a patch?
