When you put together documentation for your function reference and that reference turns out to be incorrect on two counts for one function, and the combination of those two errors makes me lose two weeks worth of work tracking down a bizarre bit of behavior, I'm bound to get a little testy.
In case you're wondering, I managed to vanquish the whack-a-mole bug. It turns out that the function that I use to reset the interrupt vector uses a different value than the one that is documented; however, when the incorrect value is used, it does not fail liek it is supposed to, but reports a success.
The end result of this was that my interrupt handler was deleted, but the reference to my interrupt handler in the kernel was not, and whenever I would enable interrupts on the system, it would crash, but only the second time. After that, the previously loaded value just happened to be correct in memory.
Doing some last-minute concrete grooming on the porch.
This involves a mix that is basically portland cement with a little bit of sand. I also used an admix that's a lot like glue. It helps to bond the concrete tighter and adds strength.
So the stuff in the mixer, add some water to make a mixture that's... well, a lot like mud.
Doing just fine most of the way. Maybe a little light on the water, so floating it off I added water in a fine mist to the top surface.
Almost to the end, and it started setting up in the mixer. So I added water.
With the mixer pointed at about a 30-degree down angle.
Ever seen an elephant with diarrhea?
I had about 30 lbs. of gooey mortar mix come loose and flop on the deck, and splatter directly onto yours truly.
Turns out that the mixture sticks really well to skin.
I just got out of the shower.
