I updated my FreeBSD/arm 11-CURRENT BeagleBone Black today and now there =
is a huge pause when booting up. The boot sequence runs normally to the =
"gpioc0: <GPIO controller> on gpio0" message and then seems to hang. A =
long time later, it continues and finishes the boot.
The lines after the paused one are these:
uart0: <TI UART (16550 compatible)> mem 0x44e09000-0x44e09fff irq 72 on =
simplebus0
uart0: console (-1,n,8,1)
The console speed of -1 looks definitely wrong.
Is a bad initialisation of the uart causing the long boot delay?
I've included the boot log at the end of this message.
Cheers,
Paul.
