Hello Eli, I will repeat the test such that I can test whether the system still responds to ping on the Ethernet interface. Regarding the kernel logs and how to reproduce this issue: this information is present as attachments in http://bugzilla.kernel.org/show_bug.cgi?id=10890. Please let me know if you need more information.
