Hello all. After minutes or hours or days of running vdr 1.4.7, I get the following messages in my syslog: dvb_ca adapter 0: CAM tried to send a buffer larger than the ecount size! dvb_ca adapter 0: DVB CAM link initialisation failed :( When running vdr 1.6.x, the problems are even more frequent/worse and I get those: dvb_ca adapter 0: CAM tried to send a buffer larger than the link buffer size (192 > 128)! vdr: [3140] ERROR: can't write to CI adapter on device 0: Input/output error dvb_ca adapter 0: CAM tried to send a buffer larger than the ecount size! dvb_ca adapter 0: DVB CAM link initialisation failed :( The result is always the same, the CAM stops decrypting and I have to restart vdr. After a lot of searching around, I've learnt that I am not the only one with those problems and they seem to be related to multi core systems. I read that pining vdr down to one CPU core might help... and indeed it did. This cannot be a hardware related issue because... 1) meanwhile I switched from a NForce 590 SLI to a X48 chipset and thus also from an AMD64 X2 5600+ (Winchester) to an Intel Core2Duo E8400 (Wolfdale) 2) I swapped my KNC One DVB-C Plus for a new one And the problems persist. I've already written a report to the vdr list which was unfortunately ignored and besides it looks more like a dvb issue itself. I was unable to test the kernel with nosmp or similar (which was reported by others to work just fine) because I need this machine to work on. I've attached detailed informations about my system and I'd be more than happy to help fix this once and for all, so one can savely rely on vdr again. Last but not least, I am using a AlphaCrypt Light module with 3.15 firmware. Thanks a lot in advance for every help. Best regards, Matthias Dahl
