Subject: RE: 2.6.24.7-rt26 and 2.6.26.8-rt13

Hi,

I'm using kernel 2.6.26.8-rt13 with CONFIG_DYNAMIC_FTRACE=y set.
When loading a kernel object the following message appear:

BUG: sleeping function called from invalid context insmod(1370) at include/asm/uaccess_32.h:560

 =======================

Is it not possible to use rt-patches and dynamic tracepoints?
