From: Alexander Duyck Date: Wed, 13 Jan 2010 01:49:13 +0000 (+0000) Subject: ixgbe: Do not attempt to perform interrupts in netpoll when down X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1a647bd213d85c88507967104aea79b2649e6a6e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git 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.
