Sorry for replying to my own's post, as I just want to make this information available in case someone would find this mail thread later. The issue appear to be related to S470 overheating. I discovered that my S470 became very-very hot right after I power the machine up, and recently it started to freeze right after the boot. So the board was shipped to the dealer for tests / exchange, and my machine is back to normal operation (without a DVB-S2 card, temporarily). My friend's board is slightly cooler - so putting a fan blowing directly on the board seem to solve the problem for him completely (no freezes for three days now). So it's very likely to be hardware-related, and not a driver / configuration issue. -- Best regards, Andrew -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
