I have now the above problem and the lspci reports the NICs OK:
00:0d.0 Ethernet controller: Intel Corporation 82557 [Ethernet Pro 100] (rev 08)
00:0e.0 Ethernet controller: Intel Corporation 82557 [Ethernet Pro 100] (rev 08)
00:10.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8029(AS)
00:11.0 Ethernet controller: Intel Corporation 82557 [Ethernet Pro 100] (rev 0c)
00:12.0 Ethernet controller: Intel Corporation 82557 [Ethernet Pro 100] (rev 0c)
00:11.0 Ethernet controller: Intel Corporation 82557 [Ethernet Pro 100]
(rev 0c)
Subsystem: Intel Corporation: Unknown device 0040
Flags: bus master, medium devsel, latency 32, IRQ 5
Memory at f6241000 (32-bit, non-prefetchable) [size=4K]
I/O ports at dc00 [size=64]
Memory at f6200000 (32-bit, non-prefetchable) [size=128K]
Expansion ROM at <unassigned> [disabled] [size=64K]
Capabilities: [dc] Power Management version 2
Why it's now Unknown device 0040?
What can I do?
Thank you,
Cosmin
