Package: base
Severity: critical
Justification: breaks the whole system
Dear Maintainer,
*** Please consider answering these questions, where appropriate ***
* What led up to the situation?
debian squeeze box up-to-date but running kernel 3.8.13 with e1000e and tg3
interfaces with few gre tunnels and dual stack.
* What exactly did you do (or not do) that was effective (or
ineffective)?
flapping a intel or broadcom nic will result in kernel panic
* What was the outcome of this action?
kernel panic with swapper (found by crash inspection on the vmcore)
* What outcome did you expect instead?
kernel should not be affected by the interface down/up..
