>Description:
The GENERIC kernel boots properly.  Also the kernel I first compiled
operates as is expected.  Kernels crash when I try to:
-  Add supprot for the Log Structured Filesystem
-  Add support for my new Ethernet card

I get this panic report:
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x38
fault code = supervisor read, page not present
instruction pointer = 0x8:0xf017bb7b
code segment = base 0x0, limit 0xfffff, type 0x1b
             = DPL 0, pres 1, def 32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL= 0
current process = 4 (update)
interrupt mask = bio
panic: page fault

>How-To-Repeat:
Reboot the machine
>Fix:
none. I must use a kernel with just FFS filesystems and without 
ethernet support.  Compiling in other drivers (no matter which) causes
the same problem.
