Bug#997663: general: bullseye, system freezes completely when firefox freezes

[jacobkochems@gmail.com]

I just wrote an Email to the manufacturer of my "TUXEDO InfinityBook
Pro 13" and referenced this bug report. They sell specifically Linux
suited Hardware. Since they offer a Distro of their own I hope they can
shed some light on the hardware issues raised here. If there are some
special kernel parameters to be set they should know about it.

Also, I tried to provoke the system freeze with a memory bomb:
> #include <stdio.h>
> #include <stdlib.h>
> 
> #define KIB 1024
> #define MIB (KIB * KIB)
> #define ALLOC_MIB 10
> #define ALLOC_SIZE (ALLOC_MIB * MIB)
> 
> int main (void)
> {
>   int totalMiB = 0;
> 
>   printf("membomb: started\n");
>   while (1)
>   {
>     if ( malloc(ALLOC_SIZE) == NULL )
>     {
>       printf("membomb: malloc() failed, exiting\n");
>       return 1;
>     }
>       totalMiB += ALLOC_MIB;
>       printf("membomb: total memory allocated: %d MiB\n", totalMiB);
>   }
>   return 0;
> }
I tried this on AC and on Battery to no avail I'm afraid. After some
sluggish input behaviour the system kills the process, as it should.
Maybe I need to consume the memory of the graphic chip? For Intel HD
Graphics, is that even a separate thing?
