Hi 

I found a regression in 3.0.1-rt8 compared to 3.0-rt7 in RTB configuration.

The kernelconfig is attached. Plattform arm1136jfs  (pcm043).

Heres the output on booting:
Starting kernel ...

Uncompressing Linux... done, booting the kernel.
drivers/rtc/hctosys.c: unable to open rtc device (rtc0)
kernel BUG at mm/filemap.c:2043!
Unable to handle kernel NULL pointer dereference at virtual address 00000000
