As I said yesterday, I have no /sys/class/leds directory, probably because I cannot load
any led module. Actually I haven't any led-module. But If I enable leds in menuconfig,
I obtain compiled modules :
storage01:/usr/src/linux-2.6# dir /lib/modules/184.108.40.206/kernel/drivers/leds/
drwxr-xr-x 2 root root 4096 Nov 19 11:48 .
drwxr-xr-x 7 root root 4096 Nov 19 11:48 ..

-rw-r--r-- 1 root root 78594 Nov 19 11:48 ledtrig-timer.ko
If I try ro modprobe let's say led-class, I get errors:
led_class: Unknown symbol leds_list_lock
led_class: Unknown symbol led_trigger_store
led_class: Unknown symbol leds_list
led_class: Unknown symbol led_trigger_set
led_class: Unknown symbol led_trigger_show
led_class: Unknown symbol led_trigger_set_default
and the module does not load.
What I am missing ?
searching the net I find this:
When I produced zImage Actually I haven't leds selected: do you think I can try to
recreate zImage ?
