Also decreases the amount of work done in IRQ context. The patch seems to work insofar as a patched driver still "works". It's possible to descramble the CA channels I have access to, and I haven't experienced any hard crashes. The "issue" I've seen, which is that descrambling stops working after a certain time is unchanged. As Manu Abraham suggested, this is probably a "feature", i.e. it is not a fault in any driver, but the card just needs to be "re-told" to descramble every so often. There's still a slight problem left in that regard, as even when I'm going down to re-send the CA commands every thirty seconds, it sometimes decides that this is not enough. I will try to find a good way to determine a "good" interval. -- Andreas Trottmann Werft22 AG Tel +41 (0)56 210 91 37 Fax +41 (0)56 210 91 34 Mobile +41 (0)79 229 88 55
