I just had a domU instance lock up while I was untarring a file over ssh. I connected with xm console, and got the attached (decoded) log. Let me know what other information might be helpful.FWIW, the only filesystem on the guest is XFS, and it's an lvm volume on the host. -Tupshin zuul login: Unable to handle kernel NULL pointer dereference at virtual address
