[Bug 42572] e1000 driver on thinkpad X60 doesn't auto-load, produces latency

[Scott Norris]

Public bug reported:

Affects: linux-source-2.6.15 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed


Description:
The thinkpad X60 uses the Intel 82573L Gigabit ethernet chipset, which
uses the e1000 driver. It was not noticed at all when I installed, and I
had to unload/reload the driver module using modprobe as described here:

Unlike in that thread, it seems to work fine for me on subsequent
reboots. But the strange behavior is that, if I "ping" any test site,
the response times alternate between a normal time of around 50ms, and a
long time of exactly one second.  On the thinkpad testing team page,

Florg reports that this behavior is present in other kinds of network
connections as well.  However, both Florg and myself find that large
files appear to be transferred at full speed.
