Hello Parisc-linux hackers,
I ran the lmbench mark sweet against an dual-processor A500. I have
attached the results of the benchmark for people to review.
I am not convinced of the validity of the benchmark because the
following message repeatedly showed up in dmesg:
do_page_fault() pid=22449 command='lat_sig' type=15 address=0x40019000
vm_start = 0x40019000, vm_end = 0x4001a000
