hello - i've had a system panic multiple times after rebuilding 
world/kernel today.  here's my info:
FreeBSD topanga 13.0-CURRENT FreeBSD 13.0-CURRENT 2474a68216f(master) 

Looking at two of the panic texts I see this:

Fatal trap 12: page fault while in kernel mode
cpuid = 1; apic id = 01
fault virtual address   = 0x52
fault code              = supervisor read data, page not present
instruction pointer     = 0x20:0xffffffff80f47f54
stack pointer           = 0x0:0xfffffe0122e4a6d0
frame pointer           = 0x0:0xfffffe0122e4a7b0
code segment            = base 0x0, limit 0xfffff, type 0x1b
                         = DPL 0, pres 1, long 1, def32 0, gran 1
processor eflags        = interrupt enabled, resume, IOPL = 0
current process         = 69399 (java)
trap number             = 12
panic: page fault
cpuid = 1
time = 1561514025

KDB: enter: panic

__curthread () at /usr/home/pete/git/freebsd/sys/amd64/include/pcpu.h:246
246             __asm("movq %%gs:%P1,%0" : "=r" (td) : "n" 

I have usable core files and can post any additional debug info needed.  
The first crash happened when launching chrome, the second (which is 
what the above text is from) happened when I was running a java process 
in a jail.  Has anyone else seen this?
