There are some problems with allocating too much bounce memory. If you need bounce buffers, inside of the bounce buffers calculation (#ifdef BOUNCE_BUFFERS) where the number of bounce buffers are calculated in /sys/i386/i386/machdep.c, limit the number of bouncepages to 128 instead of it's excessive value. Good luck, and give me some feedback!!! John
