While that's useful, we would also like reproduction steps. We'll need exact
hardware and software setups and the steps you took to get there. Send the full
dmesg, "lspci -vvv", eeprom dump, and registers dumps of both the failed and
passing cases.
It would be easiest if you send those as separate files and attach them to a
bug opened on sourceforge.
Thanks.

Subject: RE: C2758 i354 link issue
So I've compiled the driver with debug mode turned on, and I have two boot logs
and a log of workaround to share with you, the first one is it booting normally
and the link comes up normally without any workarounds, the second is when it
fails.
Good boot: http://repo.ezzi.net/igb1.txt
Fail boot: http://repo.ezzi.net/igb2.txt
For the most part they are very similar, until it hits
e1000_check_downshift_generic and then its totally different. The time it
worked correctly it hit:
"e1000_check_downshift_generic"
e1000_put_hw_semaphore_generic
e1000_read_phy_reg_mdic
e1000_release_phy_82575
e1000_release_swfw_sync_82575
e1000_get_hw_semaphore_generic
e1000_put_hw_semaphore_generic
e1000_check_downshift_generic
e1000_read_phy_reg_82580
e1000_acquire_phy_82575
e1000_acquire_swfw_sync_82575
VS:
e1000_put_hw_semaphore_generic
e1000_read_phy_reg_mdic
e1000_release_phy_82575
e1000_release_swfw_sync_82575
e1000_get_hw_semaphore_generic
e1000_put_hw_semaphore_generic
<this is where it changes on the failure boot>
e1000_check_for_link_82575
e1000_check_for_copper_link
e1000_phy_has_link_generic
e1000_read_phy_reg_82580
e1000_acquire_phy_82575
e1000_acquire_swfw_sync_82575
e1000_get_hw_semaphore_generic
and it will sit here looping forever:
[ 1513.308318] e1000_put_hw_semaphore_generic
[ 1513.313244] e1000_read_phy_reg_82580

[ 1514.260753] e1000_get_hw_semaphore_generic
[ 1514.265699] e1000_put_hw_semaphore_generic
Over and over and over. If I apply my workaround with ethtool, here is the
output of how it changes:
http://repo.ezzi.net/igb_workaround.txt
and then it works normally. You can also see e1000_check_downshift_generic
gets called this time.
Just for a test in e1000_macc, I commented this out:
// if (!link)
// return E1000_SUCCESS; /* No link detected */
And it did allow the network card to come up on boot on what otherwise would
have been a failed boot, but there was still a interruption in the link (it
went down then it came back up), and every 60-90 seconds it would go down
again for 10-15 seconds in a loop.
Hopefully this helps narrow it down

Kristian didn't reply to the mailing list but if you check e1000-bugs you'll
see he resolved his issues. I'm still not clear on what the problem was, but
you can check there for more details.
In any case, I'm guessing your problem isn't the same as his problem. I think I
asked him to try a different distro and I don't think he did that. I'm still
not convinced this isn't a problem with OpenWRT but then again you've never
said what OS you're running. If it is OpenWRT, have you tried a different
distro?

Subject: C2758 i354 link issue
Hi,
I'm having the same problem as Kristian is with his igb link issue. I also
have a different machine with an i210 card in it, that also has the same issue
on Linux ONLY. FreeBSD works fine.
It's about 40% chance on boot that the issue will happen (but I did find a
workaround). I believe it's something to do with auto-negotiation code. I can
either unplug/replug the cable and it will come back up, or I can force the
link speed/duplex and it will bring the link back up when the issue is
triggered.
