  1. Bug#494036: linux-image-2.6.26-1-686: same erractic freeze on my thinkpad t60 with 2.6.25 and 2.6.26

    Package: linux-image-2.6.26-1-686
    Version: 2.6.26-4
    Followup-For: Bug #494036


    Just to add another report. I have the same erratic freezes on my Thinkpad T60
    with 2.6.25 and 2.6.26. I hope this is the same problem as reported in this bug
    report but I have nothing to confirm it.

    At the moment, I cannot use a kernel > 2.6.24 because of those freeze.

    Feel free to ask for more details or tests if needed.
