npxdna causing kernel traps

Hello List,

Thought I'd quick bounce this off the list before I submitted a bug 
report.

I have a fresh install of 5.2.1 which i then upgraded to -current.  I'm 
now getting the following message scrolling on the console

kernel trap 22 with interrupts disabled
kernel: npxdna: fpcurthread == curthread X times

Where X is N+1.  Eventually I get a kernel panic and the machine has to be 
rebooted. I get this in a custom kernel as well as GENERIC. This is with 
the src from Midnight CDT. Generic kernel spits out watchdog noticed and 
the network doesn't work both with and without ACPI, but that's for 
another email.

here's my info. The trap info is simliar every time and happens while I'm 
building ports.  The one below is when I was running `make clean`

Thank you

Rob
