This got me wondering...is it possible to have the package version show up in the log, rather than the upstream/ABI version?

Matt, this looks like the same crash you sent me at UDS. I'm going to open an upstream bug about this.

I'll update to it, naturally, but I haven't seen this happen recently.
What's the patch?

Because this system has an IPW2200, which I rely on for daily work, I can't
do this until there is an LRM available for that kernel.

Someone needs to process those then. I don't know why you need lrm for
ipw2200 though, the firmware is in linux-ubuntu-modules.

I'm not clear on why it moved out of linux-image; I assumed it was to
accomodate stricter licensing guidelines. If it's in linux-ubuntu-modules,
I can upgrade, as that seems to be available.
