Title:
eth0 suddenly disappears with sky2 driver
Status in “network-manager” package in Ubuntu:
Confirmed
Bug description:
After sometime the PC is on if not used the eth0 interface simply
disappears.
Doing some further investigation I realized that this device isn't listed on
udev net.rule, as I did have the MAC address info of the "ghost" interface I
have added an entry in that config file and they I tried to unload/load the
sky2 driver in order to check what would happen.
Curiously after doing that I've got the following message in dmesg
dmesg
[ 5328.995899] sky2: driver version 1.30
[ 5328.996384] sky2 0000:02:00.0: setting latency timer to 64
[ 5328.996445] sky2 0000:02:00.0: unsupported chip type 0xff
[ 5328.996484] sky2: probe of 0000:02:00.0 failed with error -95
As follows below the detail about the interface which were supposed to
be working as eth0:
lspci
02:00.0 Ethernet controller [0200]: Marvell Technology Group Ltd. Yukon
Optima 88E8059 [PCIe Gigabit Ethernet Controller with AVB] [11ab:4381] (rev 11)
Subsystem: Hewlett-Packard Company Device [103c:1456]
Kernel modules: sky2
As shown below, nothing appears regards eth0 even on ifconfig -a,
however I can see that it is still there in lspci.

I guess it may be an error related to sky2 or network-manager, I'll do
further check and then I'll post the results in here.
Please let me know in case further details are required, i hope it helps.
thanks.
