From 4529819c45161e4a119134f56ef504e69420bc98 Mon Sep 17 00:00:00 2001 From: Breno Leitao Date: Fri, 18 Dec 2009 20:29:04 -0800 Subject: bnx2: reset_task is crashing the kernel. Fixing it. If bnx2 schedules a reset via the reset_task, e.g., due to a TX timeout, it's possible for the NIC to be disabled with packets pending for transmit. In this case, napi_disable will loop forever, eventually crashing the kernel. This patch moves the disable of the device to after the napi_disable call.
