My thinkpads continue to panic at boot with memory use after free when
probing the DVD drive. I've been rolling back ata-queue.c to 1.39 to
correct the problem. From a working boot:

aku# dmesg|grep ata

When I told you this you said your code base had diverged too far from
CVS to attempt to diagnose the problem.  Perhaps you have something else
yet to commit that will remedy this?
