   Please provide the EXACT kernel message. I can't help you without that.
I see that people have already pointed out that the above should be:

options		"MAXMEM=393216"

   ...as the arithmetic may not work as intended. Be sure the kernel reports
the proper amount of memory in the startup message. Also, it is not necessary
to send messages like this to multiple mailing lists. hackers or questions
would have been sufficient.
