Hello,

I recently posted a message here about a kernel page fault trap with 
1.6T/i386. Yesterday (july 1st) I built a new kernel with the latest 
sources (kernel is now 1.6U) and ran into the same problem again. Manuel 
Bouyer suggested I post the output of "tr" the next time it happens so 
here is that information:

uvm_fault(0xd3ec4780, 0, 0, 1) -> 0xe
kernel: page fault trap, code=0

Does this help anyone understand the problem?
