I'm now looking at dvb_ca_en50221.c and I'm pretty sure the solution is in here and not in budget-av.c. Somewhere around line 270 is a thing that loops in a while and breaks after timeout. I removed the break (so it keeps looping). Now I see the following when I insert a CAM: [ 71.764000] budget-av: cam inserted A [ 82.144000] dvb_ca adaptor 0: PC card did not respond :( So at least there's no more infinite loop with ejected-inserted-ejected and so on. But it doesn't work either. It reaches DVB_CA_SLOTSTATE_WAITREADY and times out there. From there it should automatically change state, but it doesn't. Now I'm getting a little stuck, because I don't really know what it's doing and what piece really gets stuck. I also removed the timeout from slotstate_waitready, now I don't get errors anymore, but it (of course) doesn't work. And I broke the ability to eject the CAM, I'm guessing it's stuck in a loop after I ejected and re-inserted the CAM. _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
