Comment 18 for bug 253004

Ok, I tried to follow the KernelTeamBugPolicies reporting instructions to attach to this existing bug report, but they appear to be wrong: at least for hardy LTS, apport-collect doesn't seem to exist.

If Ubuntu is serious about LTS releases, this bug needs to be fixed.

Here is a quick summary--in lieu of a full bug report--to basically say "me too":
