description:
Increase the size of softint's data to prevent panic on big machine. Nowadays,
some device drivers and some pseudo interfaces allocate a lot of softints. The
resource size for softints are static and it panics when it execeed the limit.
It can be dynamically resized. Untill dynamically resizing is implemented,
increase softint_bytes from 8192 to 32768.
