Public bug reported:
We have a server (Dell R715) with two Intel x520 NIC's. If we run Ubuntu
12.04 on it, the NIC's works flawlessly (with stock kernel driver or
with Intel compiled one), but if we upgrade release to 12.10, 13.04 or
13.10, the NIC's stop working: either stock or Intel drivers fails with
error:
[ 226.395766] Intel(R) 10 Gigabit PCI Express Network Driver - version 3.18.7
[ 226.395770] Copyright (c) 1999-2013 Intel Corporation.
[ 226.395980] ixgbe: probe of 0000:22:00.0 failed with error -5
[ 226.396092] ixgbe: probe of 0000:22:00.1 failed with error -5
[ 226.396203] ixgbe: probe of 0000:23:00.0 failed with error -5
[ 226.396311] ixgbe: probe of 0000:23:00.1 failed with error -5
I contacted Intel developers and they responded:
"Hey Fernando,
We (ixgbe) only returns EIO (error 5) for a couple of reasons.
1) When we fail to io map (ioremap)
2) If the eeprom checksum is incorrect.
3) If the MAC address from the checksum is invalid
Reasons 2 and 3 are related to the NIC's eeprom so if they worked with another
system they should still be fine now. If you really wanted to verify you could
try out the NIC's on a known good system again to see if the eeprom somehow got
corrupted.
That pretty much leaves us with ioremap returning an error. I'm not at all
sure why your Ubuntu release would not like the way we are calling ioremap, but
it might give you a place to start looking in Ubuntu changes.
Thanks,
-Don"
If the server boot with kernel 3.2.0-55 (from grub menu) both NIC's
works fine.
Please let me know how can I help!
Regards
Fernando
