loop on reset adapter with ixgbe

loop on reset adapter with ixgbe

Hi,

On some machines with a network card named
"Intel Corporation 82599EB 10-Gigabit SFI/SFP+"

At boot time, I'm getting an infinite loop showing these messages:

ixgbe 0000:03:00.0 eth0: initiating reset to clear Tx work after link loss
ixgbe 0000:03:00.0 eth0: Reset adapter
ixgbe 0000:03:00.0 eth0: detected SFP+: 3

ethtool info:
driver: ixgbe
version: 3.8.21-k
firmware-version: 0x00000000

I'm using the last linux stable branch v3.10.x.

I need to unplug/plug the network/cable (a twinax cable) several times to
stabilize the situation and get some network.
I was wondering if I should consider this as a driver/firmware bug or if I
should look for a physical issue (I changed the physical cable several times).
Or do you need some more info to help understand this issue?

Best regards,
-- 
William

Hey William,

Thanks for letting know what you're running into, however I don't remember ever seeing a failure quite like this.  I'm wondering if it is something we might have fixed in later versions of the driver.  By any chance could you see if you get the same failure with the latest source forge driver?  It will make it easier to track down if we are looking for something we already fix or a new problem altogether.

Thanks,

Thank you for your quick reply.

I am unfortunately getting the same result with ixgbe 3.18.7 compiled
with a linux kernel v3.10.x

Sorry for my late answer,

I also just noticed your firmware looks in correct.  What is the DevID for your device?  Likewise do you have another NIC and if so could you check it's firmware-version?

might be a stupid question, but which id are you talking about? How can
I get it?

I have some NIC with the same firmware without any problem.

[Tantilov, Emil S]

Could you please send the complete output from dmesg along with the stats (ethtool -S) from the interface and also your .config from your kernel?

You can send the attachments directly to me or Don, or better yet open a bug at e1000.sf.net if possible.

Thanks,
Emil

FW: loop on reset adapter with ixgbe

Hey William,

A quick why to get the device ID would be to:

First get the PCIe bus address from "ethtool -I <port>"

[root@dcsworkstation src]# ethtool -i p258p1
driver: ixgbe
version: 3.11.33-k
firmware-version: 0x18eb0001
bus-info: 0000:05:00.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: no

Then use that address to find the device ID:

[root@dcsworkstation src]# lspci -ns 0000:05:00.0
05:00.0 0200: 8086:10fb (rev 01)


As for the FW version I'm concerned that yours might not be correct from the output you sent me earlier.

> ethtool info:
> driver: ixgbe
> version: 3.8.21-k
> firmware-version: 0x00000000

This doesn't look correct to me I will poke our FW folks to verify.  It may be worthwhile to dump the FW and send it to me (i.e. ethtool -eeprom-dump).

Thanks,
-Don

p.s. I'm about to be out of the office until Tuesday of next week and am not sure I'll be able to get to my email so I might be slow in a reply.  :(

Hi Skidmore,

Sorry for the late answer, I needed to wait for a physical access.

for me it is:
03:00.0 0200: 8086:10fb (rev 01)

> As for the FW version I'm concerned that yours might not be correct from the output you sent me earlier.

or might be a userland issue (ethtool not reading the correct part?)
