Subject: 2.6.30.1: BUG: sleeping function called from invalid context at
	include/linux/kernel.h

HHi,
on one of my testing machines running 2.6.30.1, I noticed following:

[43601.016119] BUG: sleeping function called from invalid context at include/linux/kernel.h:155
[43601.016123] in_atomic(): 1, irqs_disabled(): 0, pid: 2197, name: zip

Apparently, there is something wrong in the nf_log code...
