And at this point, I can't tell. This reboot was from a cold start, without
the argument, and cold by long enough to make the rounds about the house and
pick up a beer, but not take my evening pillbox. A minute cold, maybe 2 max.
The log is clean since except for a kudzu nag of some sort:

[ 50.535388] warning: process `kudzu' used the deprecated sysctl system call
with 1.23.

which isn't your problem, but fedora's.

As I said before, that error has not returned since the first time I used that
argument, and I have booted several times now without it. Uptime now is just
over an hour though, so I'm not taking bets just yet. :)

Cheers, Gene

I pray the double lock will keep;
May no brick through the window break,
And, no one rob me till I awake.
