Here pre8, pre8 with any of the Rik patchs and pre9-1 looks bad.  If I
ran mmap002 in that machines it will be killed allways, now a lot of
times in around 30 seconds (in previous kernels the tests lasts around
3 min before being killed).  The system continues doing kills until
init dies, then all the system freezes, no net, no ping answer, no
keyboard answer (sysrq didn't work).  No information in logs, except
that some processes have been killed, no messages in the console
either.  If you need to reproduce the efect is easy, here in less than
5 min mmap002 test, the system is frozen.

If you need more information, let me know.

Later, Juan.
