It may be a problem of saa7146_wait_for_debi_done(). Without a CI/CAM, every debi read/write request ends with an error. In this case, SPCI_DEBI_S will never go low. Most of the debi requests are done with an spinlock held. Saa7146_wait_for_debi_done() polls for 250msec the PSR. Possible, this is the reason for the high load. Usually, saa7146_wait_for_debi_done() can bail out earlier, if SPCI_DEBI_E is set. saa7146_wait_for_debi_done() is also used by the TT-FF cards. During the booting of the ARM, this cards need the timeout/wait after a debi error. - Hartmut _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
