linux driver (ver. 110531) breaks IR functionality on 2.6.38

[sukkubus]

hi,

after installing the tbs driver on my 64-bit ubuntu 11.04 server (kernel 2.6.38-8 x86_64) i get the following output from dmesg:

Code: Select All Code

rc_core: exports duplicate symbol ir_raw_handler_unregister (owned by ir_core)


the tbs-driver makes it impossible to load IR related kernel modules:

Code: Select All Code

modprobe: FATAL: Error inserting rc_tbs_nec (/lib/modules/2.6.38-8-server/kernel/drivers/media/rc/keymaps/rc-tbs-nec.ko): Invalid module format
modprobe: FATAL: Error inserting ir_nec_decoder (/lib/modules/2.6.38-8-server/kernel/drivers/media/rc/ir-nec-decoder.ko): Invalid module format
modprobe: FATAL: Error inserting ir_rc5_decoder (/lib/modules/2.6.38-8-server/kernel/drivers/media/rc/ir-rc5-decoder.ko): Invalid module format
modprobe: FATAL: Error inserting ir_rc6_decoder (/lib/modules/2.6.38-8-server/kernel/drivers/media/rc/ir-rc6-decoder.ko): Invalid module format


according to jarod from the mythbuntu community this might be a problem, because ir_core became rc_core on 2.6.38 (see http://www.gossamer-threads.com/lists/mythtv/users/481981)

It looks like their driver would probably work fine with circa 2.6.36 code,
but is broken on .37 and on, as ir_core became rc_core. Your system currently
has two competing eras of kernel code from drivers/media/ trying to run at
the same time.

@tbs-team: it would be great if this issue will be fixed soon, because IR devices can not be used in conjunction with the tbs driver...

best regards

mceusb device?

jarod thinks https://patchwork.kernel.org/patch/930442/ is the problem & and fix!
im not sure what todo with that - i'm just waiting for further info in that report and for the status to turn to 'completed/applied'.

i guess it will need an update of v4l - im not sure if this will be in the TBS scope or not. if i've understood cody correctly, then TBS have disabled something that needs to be re-enabled.

edit: i've just seen theres a new driver out; http://www.tbsdtv.com/english/Download.html
110710 dated - might be worth trying that at it seems to fix a few things and do something with MSI (MSI is reference in the above bug report).
do report back if that fixes things; a few people here and on mythtv user mailing list are looking for a solution.
(if i were to try it, i'd need to wipe my existing mythtv install)
