>Description:
When using the interface fxp0 with PAE enable in kernel, occurs the following error:

fxp0: can't map mbuf (error 12)
..

it repeats, repeats and lost communication.

Responsible-Changed-When: Sun Mar 23 11:45:57 UTC 2008 
Responsible-Changed-Why:  
Over to -net.  fxp doesn't seem to work correctly with PAE, 
even though it is fxp not excluded from the PAE kernel (ie so 
should work)

State-Changed-When: Tue Jun 23 08:30:24 UTC 2009 
State-Changed-Why:  
There was a couple of bus_dma(9) fixes in HEAD which may fix the 
issue on PAE environments. Could you try latest fxp(4) in HEAD? If 
you're using 7-stable or 7.2-RELEASE you can just copy if_fxp.c, 
if_fxpreg.h and if_fxpvar.h files from HEAD to 7-stable/7.2-RELEASE 
and rebuild kernel.
