Comment 6 for bug 46680

Paul, when the machine freezes it is really completely freezed, there's no way to recover from that state, it is not an X server failure.
No SSH and no Alt-SySrq can help, the kernel is dead.

Also as I already posted on the connected bug (# 43114) it was perfectly working before I changed the partiotion layout of the HD, and now it is not working anymore (no software has changed, no drivers no nothing).

There's nothing in the Xorg.0.log or messgaes file about the failed boot.

(the following command is what you requested but it shows the ethernet card)
