From b43e867a022c55c1bfebcf08ac96e6bd0367b67a Mon Sep 17 00:00:00 2001 From: Bruce Allan Date: Fri, 21 Jun 2013 09:07:18 +0000 Subject: [PATCH] e1000e: disable ASPM L1 on 82583 The 82583 can disappear off the PCIe bus. This device is a modified 82574 which had the same problem which was fixed by disabling ASPM L1; disabling it on 82583 fixes the issue on this device.
