NetXtreme BCM57786 Gigabit Ethernet PCIe not showing up

My laptop's ethernet adapter is completely not showing up. The adapter shows up on the pci bus:

01:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM57786 Gigabit Ethernet PCIe (rev 01)
	Subsystem: Acer Incorporated [ALI] Device 0775
	Flags: bus master, fast devsel, latency 0
	Memory at b0410000 (64-bit, prefetchable) [size=64K]
	Memory at b0420000 (64-bit, prefetchable) [size=64K]
	Expansion ROM at b0430000 [disabled] [size=2K]
	Capabilities: [48] Power Management version 3
	Capabilities: [50] Vital Product Data
	Capabilities: [58] MSI: Enable- Count=1/8 Maskable- 64bit+
	Capabilities: [a0] MSI-X: Enable- Count=5 Masked-
	Capabilities: [ac] Express Endpoint, MSI 00
	Capabilities: [100] Advanced Error Reporting
	Capabilities: [13c] Device Serial Number 00-00-20-89-84-78-34-a7
	Capabilities: [150] Power Budgeting <?>
	Capabilities: [160] Virtual Channel
	Capabilities: [1b0] Latency Tolerance Reporting

but it does not show up as an adapter:

 ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: wlp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DORMANT qlen 1000
    link/ether 24:fd:52:40:f1:49 brd ff:ff:ff:ff:ff:ff

Googling around, it seems that the module for this device is tg3, but loading this module manually doesn't change anything.


If anyone has any ideas, please let me know. I'm willing to post the output for any diagnostic commands people might suggest smile

Re: NetXtreme BCM57786 Gigabit Ethernet PCIe not showing up

I had the same problem and found this Ubuntu bugtracker:
https://bugs.launchpad.net/ubuntu/+sour … ug/1182868

Since I am using the mainline kernel anyway to get my touchpad working I just applied the patch from the bugtracker before building the kernel and it worked!
