The message is "Too much work at interrupt 0{something}"?  

If so, how specify the value of max_interrupt_work?  The default value
of max_interrupt_work is 40, and it is too small to process a lot of
frames on burst transfer.

Try to increase this value as follws.

# insmod hamachi.o max_interrupt_work=10000 

Or try larger numbers.  We use max_interrupt_work=10000 or 30000 on
Alpha XP-1000 and Pentium II 400MHz boxes on linux 2.2.[579].
