[parisc-linux] Forcing PA-Linux to swap / do_page_fault()

[Chuck Slivkoff]

Greetings all,

I've noticed a problem that I believe is might be related to the kernel
not being able to use swap space.  I've never seen swap utilization > 0
and suspect that something might be seriously wrong. Here's an example
of the kernel error:


do_page_fault() pid=8730 command='Xvfb' type=6 address=0x00000003

My system is a 712/60 with 128MB RAM.

Does anyone have a good example of test to force the system to use swap?
