I have 2 issues with 4.0-CURRENT. The first is the plethora of
"microuptime() went backwards..." errors that scroll on my console.
The second is that I have DDB compiled into my kernel (and a USB keyboard)
either on vga or serial console, if I trip DDB (control-shift-esc), I will
either get the ddb> prompt or the system will hard lock. Below is my
dmesg and kernel config. Help is appreciated.
