Hello.

I ran across this while testing my driver. I forgot to check for mmap
failure for one case, and it returned -1.
trying to access this space just hung this process, rest of system is fine.
is this a known problem?

i tried a simple program like

main()
{
int *ptr, i;
printf("reading illegal ptr\n");
ptr = (void *) -1;
i = *ptr;
}

this program never dies or can be killed.? this is 2.2 kernel on 2.0.36 this
one core dumps as expected...

Cheers,
ashokr

Plug-and-Play is really nice, unfortunately it only works 50% of the time.
To be specific the "Plug" almost always works.
