In the past there were some problems with KNC1 DVB-S cards. You might check whether one of the following modifications helps for DVB-C: (1) enable master reset in saa7146_core.c (line 354) If it still does not work: (2) slow down I2C speed: replace SAA7146_I2C_BUS_BIT_RATE_120 by SAA7146_I2C_BUS_BIT_RATE_480 in budget-core.c Please report back if one of these changes fixes your problem.
