    Subjecte1000e fails after several S3 resumes (2.6.26 Debian, TP T60)
    Date
    From
    Once in a while after resuming from S3 sleep, the Ethernet driver
    gets confused, whereupon dhcp'ing for an IP address fails, e.g.

    /* doing the dhcp: */
    Listening on LPF/eth0/00:16:41:52:50:de
    Sending on LPF/eth0/00:16:41:52:50:de
    Sending on Socket/fallback
    DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 7
    /* and so on with various intervals */

    I workaround it with

    modprobe -rv e1000e ; modprobe -v e1000e
    (the '-v' options to make sure the module does vanish and return)

    and then try again to get an address, which works. A similar failure
    mode happens with the iwl3945 driver (and a similar workaround usually
    succeeds).

    How can I debug this issue the next time that it happens (it's about
    once every two weeks)? Using 'ethtool' or 'lspci -vvvv'?

    $ uname -a
    Linux approx 2.6.26-1-686 #1 SMP Thu Oct 9 15:18:09 UTC 2008 i686 GNU/Linux

    It's Debian unstable's kernel 2.6.26 based on 2.6.26.4. The laptop is a
    Thinkpad T60 whose network controllers are given by lspci as

    02:00.0 Ethernet controller: Intel Corporation 82573L Gigabit Ethernet Controller
    03:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)

    Could it be caused by the kernel (and modules) getting upgraded
    underneath a running system? In which case I'll just 'not do that
    again' as the simplest fix, and reboot after a kernel upgrade. My
    installed kernel is based on 2.6.26.6, but the running kernel is based
    on 2.6.26.4 [where based on means 'with Debian's patches'].

    Please CC me on any responses.
