Problem with s3c24xx pwm driver

I'm encountering very strange problem with s3c24xx pwm driver. I'm using it 
with pwm-bl driver. When backlight level is 0, pwm-bl calls pwm_config(0, 
period); pwm_disable(), otherwise it calls pwm_config(duty, period); 

Problem is that after pwm was disabled, it can't be enabled with 
pwm_config(duty, period); pwm_enable() for some (but not all) _valid_ 
duty/period combinations.

pwm-bl works fine if pwm_disable() call is commented out.

Does anybody know how to solve this problem? Any suggestions?
