Comment 6 for bug 605045

Same here, 64bits.

This does not look like a real workaround. As you can read in redhat's bug report (https://bugzilla.redhat.com/show_bug.cgi?id=566389), it is related to r8169 module trying to allocate four pages of physically contiguous
memory. And from my logs, it makes sense:

I think we should assign this to kernel team.
