Boots. Runs. But hung hard during the "make dep" portion of the build.
Not far into it either. Had to stop and clean drives.

Boots and runs too. I'll let this one run 'till it dies.

I'm all for that. What can I do to help?

One more thing. I lost some of my earlier kernels due to a disk crash
last night. In replacing them from source I discovered that .81, .82,
.83, and .84 all die with "Aiee, interrupt in swapper task..."
There was a minor work-around for this back then. Do you remember what
it was. I'd like to go back through those kernels and verify that the
load problem I saw started at .85. One of my production machines has
locked twice in the middle of a model resolution. It was running .83
at the time. I've dropped it back to the 2.0 series kernel since it's
extra HW isn't in use right now. At any rate, I'd just like to run
what ever the most stable of that pre-85 series. Anyone remember which
was most solid of the .8x kernels?
