I had that problem on the 0216 -GENERIC kernel. I also did not have DDB
or dumping available -- the machine would bite when it first attempted to
swap -- supervisor read, page not present, etc. As soon as I stuck a
custom kernel on the machine (with DDB), it stopped happening. If there
is interest, I can turn on a dump device and boot the GENERIC kernel again
and see what happens. To trigger it, all I needed to do was have it swap
a little bit:
#include <stdlib.h>
void main(void)
{
int i;
char *b;
while (1)
{
b = (char *) malloc(8192);
for (i = 0 ; i < 8000; i += 5)
{
b[i] = '\1';
}
}
}
