From 1a647bd213d85c88507967104aea79b2649e6a6e Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Wed, 13 Jan 2010 01:49:13 +0000 Subject: ixgbe: Do not attempt to perform interrupts in netpoll when down This patch resolves issues seen when running netconsole and rebooting via reboot -f. The issue was due to the fact that we were attempting to perform interrupt actions when the q_vectors and rings had already been freed via the ixgbe_shutdown routines.
