printk in syscall

[Sourav Sen <sourav@csa.iisc.ernet.in>]

Hi,
	I encountered a strange situation!! I implemented a system
call(This is purely academic and I know that implementing system call is
not encouraged etc, etc.. :). The call is working fine. I have put one
printk in the system call routine proper(and  many others in the routines
in the call chain from the system call), for debugging purpose. The
printk prints an error situation(obviously!!). 

	When the syscall is invoked, and it is working properly, so the
printk doesn't speak, but while I bring that kernel down, that printk gets 
executed many times (as many as 22 times as per /var/log/messages). No
other printk among the ones I introduced gets executed. 

	I think this is quite strange, anybody have any idea what might be
happening.

Thanks
sourav
