Hi.
Sorry for my english.
I have an imx6 board with linux kernel 3.10.17. I use own patches to support my board.
I have lircd driver and lirc_wand module for support ir remote send signal.
When i send command after booting linux all works well. All commands are sent correctly.
But after it i  suspend my board ( echo mem > /sys/power/state) and then resume my device by pressing keypad ,
and send ir commands again.
When i  send signal , I see on receiving device that  signal corrupted. For example Instead of key 'M' ,which i send, device get '/' or receive  nothing!
I tried stop demon lircd and rmmod lirc_wand before suspend linux and restart them after resume, but its not help.
I am stucked. Pls help with this problem. 

Thanks to all.
Felix Tsaruev.

Hi Felix

one can try to debug it checkng clocks for example with dump-clocks.sh :

Is there a i.MX6 clock tree tool similar to the i.MX35 one? 

pay attention to suspend-imx6.S, clk-imx6q.c

linux-2.6-imx.git - Freescale i.MX Linux Tree 

linux-2.6-imx.git - Freescale i.MX Linux Tree 

Best regards
igor
