I just ran depmod to make sure things were straight in this dept. kepler ~ # depmod -F System.map -e -av 2.6.39.3 There are no reported errors. The modules rc-imon-mce.ko, rc-imon-pad.ko and imon.ko depend only on rc-core.ko according to the output. There don't seem to be any explicit dependencies to the keymaps (not a kernel dev so I don't know if there should be) >> I just tried this: >> >> kepler ~ # rmmod rc_winfast ir_lirc_codec lirc_dev ir_sony_decoder >> ir_jvc_decoder ir_rc6_decoder ir_rc5_decoder ir_nec_decoder >> >> kepler ~ # modprobe -v rc-imon-pad >> insmod /lib/modules/2.6.39.3/kernel/drivers/media/rc/keymaps/rc-imon-pad.ko >> >> kepler ~ # modprobe -v rc-imon-mce >> insmod /lib/modules/2.6.39.3/kernel/drivers/media/rc/keymaps/rc-imon-mce.ko > ... >> kepler ~ # modprobe -v imon debug=1 >> insmod /lib/modules/2.6.39.3/kernel/drivers/media/rc/imon.ko debug=1 >> >> with the same crash (below).

I can only see the "T.889" string in the System.map, kernel binary and kernel/sched.o (but not the source?). I have sent the config file off-list to Jarod. I will try a Gentoo out-of-the-box kernel config when I finish work also. Thanks once again for your time Regards, -- Chris Williams Brisbane, Australia
