 On Tuesday 2008-06-10 11:35 +0000, Andrew Doran output:
 : A good start would be to "set print pretty on" and print the out the uvm_map
 : structure being passed to one of the uvm_map() functions.
 
 OK, doesn't mean much to me :-)
 
 BTW, machine has 2GB memory (I chucked on the dmesg at the bottom in case any
 of it may be relevant)

 Geoff
