My apologies if this is the wrong mailing list for this question, but
recently the 82566DC-2 NIC on my Intel DP35DP mainboard stopped being
recognized by linux (Ubuntu 12.04/12.10) although the card is still visible
in lspci. e1000e tries to load but does not bring up the card The issue
was at least partly related to a worn out BIOS battery as replacing it
seemed to change behavior. Before replacing the battery, the NIC would
only come up after entering BIOS Setup. After replacing the battery the
NIC will come up after a warm reboot. If the system is powered down for
more than a few minutes, the card will not be recognized by the e1000e
driver (2.0.0-k in Ubuntu although 2.1.4 exhibits the same behavior). If
the card is recognized by Linux it will work without problems.
In a non-working state the card appears in lspci as:
00:19.0 Ethernet controller: Intel Corporation 82566DC-2 Gigabit
Network Connection (rev 02)
Subsystem: Intel Corporation Device 0001
Flags: fast devsel, IRQ 20
Memory at e3200000 (32-bit, non-prefetchable) [size=128K]
Memory at e3224000 (32-bit, non-prefetchable) [size=4K]
I/O ports at 30e0 [size=32]
Capabilities: [c8] Power Management version 2
Capabilities: [d0] MSI: Enable- Count=1/1 Maskable- 64bit+
Capabilities: [e0] Vendor Specific Information: Len=06 <?>
Kernel modules: e1000e

Kernel driver in use: e1000e
Kernel modules: e1000e
I am trying to determine if this is a HW failure or if there is a driver
bug. Any advice on how to debug further?
Thank you very much.
