I want to flash a kernel onto my N810 but every time I try I just get the Nokia startup screen for a minute then the phone shuts off. Here is what I do to make my kernel:

[sbox-ARMEL: ~] > wget http://repository.maemo.org/pool/os2....0.orig.tar.gz
[sbox-ARMEL: ~] > wget http://repository.maemo.org/pool/os2...osso71.diff.gz
[sbox-ARMEL: ~] > wget http://repository.maemo.org/pool/os2...1.0-osso71.dsc
[sbox-ARMEL: ~] > dpkg-source -x kernel-source-rx-34_2.6.21.0-osso71.dsc
[sbox-ARMEL: ~] > cd kernel-source-rx-34-2.6.21.0
[sbox-ARMEL: ~/kernel-source-rx-34-2.6.21.0] > patch -p1 < kernel-arm-kprobes.patch
[sbox-ARMEL: ~/kernel-source-rx-34-2.6.21.0] > make nokia_2420_defconfig
[sbox-ARMEL: ~/kernel-source-rx-34-2.6.21.0] > make oldconfig
[sbox-ARMEL: ~/kernel-source-rx-34-2.6.21.0] > vi .config

I modified these entries to the .config file
CONFIG_RELAY=y
CONFIG_DEBUG_FS=y
CONFIG_DEBUG_INFO=y
CONFIG_KPROBES=y

[sbox-ARMEL: ~/kernel-source-rx-34-2.6.21.0] > make oldconfig
[sbox-ARMEL: ~/kernel-source-rx-34-2.6.21.0] > make zImage
./flasher -f -k zImage

This all happens and I get no error or anything so I assume it works fine and my kernel is made but like I said above when I finish the flash my phone just gets stuck on the Nokia startup screen.

Any help is greatly appreciated!
