Subject: e1000e crashes with 2.6.34.x and ThinkPad T60

Hi,

I have a new notebook, a Thinkpad T60, which is freezing in random
intervals (like 30 minutes to two days) as long as I am using the
on-board wired ethernet interface, which is an e1000e, [8086:109a]. As
long as I keep using the WLAN, the system runs for weeks despite
frequent suspend/resume cycles etc. The crashes seem really to be tied
to using the wired ethernet. This is a hard freeze, with nothing
happening on the system, only a long push on the power button helps.

Additionally, sometimes, probably after suspend/resume, the wired
ethernet does not come up properly again, ip addr claims "NO CARRIER"
even if the LEDs on the interface and on the switch claim that there
was a link. No packets are received by the interface when it's at this
stage.

Both issues appear with 2.6.34 and 2.6.34.1. I didn't try any of these
issues with an older kernel, 2.6.34 was already out when I started
using the T60.

To rule out defective hardware, I have tried with a second T60, with
the same results.

Full dmesg and lspci-nn attached, please say if you need more.

Greetings
Marc

P.S.: Please Cc: me on replies, both linux-kernel and netdev are too
big for me to timely follow. I am subscribed to both lists, but a Cc
helps in getting a faster reply.

Adding e1000-devel (the Intel LAN developers list).

Please supply the full dmesg you meant to attach with the original report, as well as the output of lspci -vvv.

Thanks,
Bruce.

When the crashes occur - is there a trace on the screen?

Do you know of a way to reproduce the issue? For example were
you downloading files, browsing internet, or using the ethernet device
in any way when the system crashed?

I got a T60 notebook running on 2.6.34.1 and will try to reproduce in house.

Doesn't seem that there were any attachments to this email.
Could you also provide the kernel config?

Not that I can see any. I'm working in X11, and the screen simply
freezes. Mouse doesn't move any more, clock stops. System is not
pingable, does not react to Ctrl-Alt-Bksp nor to any Magic Sysrq, nor
does it shut down when I have the power button issue an acpi shutdown
event.

Sadly, no. I have it happen when typing in a remote ssh session, while
on the other hand hundreds of megabytes can be downloaded just fine.
It just happens "at random", two or three times a day. I have resorted
to using the WLAN instead of the wired ethernet, but that's not a
long-term solution.

I forgot, sorry.

Attached as well.

Can you please post the output of dmidecode?

We have a tool that you can use to dump the registers from the port in the failed state:
http://sourceforge.net/projects/e1000/files/Ethregs%20-%20Register%20Dump%20Tool/ethregs-1.12.3/

I have not been able to reproduce any of the issues you reported on T60 here in the lab, so we need to start looking into more details.

Also, could you please file a bug at e1000.sf.net with all the information you provided so far?

Thanks,
Emil

Attached, for an interface in the working state. I'll deliver another
regdump when I see the issue again.

Will do in the next days.

I guess it would be better to file two bugs, one for the crashes and
one for the no-link-in-some-situations issue, right? Or is it likely
that they both have the same cause?

After reviewing the output from dmidecode I determined that your model T60 is slightly different than mine. It appears that you have the widescreen version. Is that correct?

Also you seem to be running a fairly old version of the BIOS (1.08). The latest is 1.18:
http://www-307.ibm.com/pc/support/site.wss/MIGR-67020.html

I would recommend that you upgrade your BIOS. If that does not help we can continue with the investigation. I will also try to locate a widescreen T60 that would hopefully help me with the repro.

The model I have has been running all kinds of stress since you first reported this issue, and so far is rock solid.
