At this point, I’d need to feed you some kernel patches that will dump out more info, but you’d have to compile them and get them onto your boot media.  Is that a possibility?

I don’t know of any docs for doing custom releases, and it looks like it’s harder than it used to be to insert custom patches.  That said, I recommend doing the following on your 11.x build system:

1.  Do a clean `make buildworld` with an up-to-date tree
2.  change into the `release` directory that you just did the buildworld from
3.  `sudo make release NOPORTS= NODOC= CHROOTDIR=/usr/tmp/release SRCBRANCH="base/stable/11_at_rHEAD”`

You can set CHROOTDIR to whatever you want that has a few GB of space, but remember where you’ve set it for later steps.  This will build a release with stock sources.  Let it complete, both to prepare for the next step and to ensure that it works.  It’ll take an hour or two depending on your machine speed

4.  Take the patch that I’ll send you shortly and apply it to $CHROOTDIR/usr/src
5.  `sudo make memstick NOPORTS= NODOC= SRC_UPDATE_SKIP= CHROOTDIR=/usr/tmp/release`
