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?

Please also provide an eeprom dump from the wired LOM via 'ethtool -e ethX'.

Thanks,
Bruce.--
