Hello List, after changing my system to newer hardware (and use the latest driver for af9015), it seems the device didnt get a lock sometimes (mostly in the case the system is started up). I use the stick together with mythtv. If i get the partial lock, i restart mythbackend or switch channel - then i get the lock. If i get it just the first time the stick is working fine for the whole day. Only the very first channelpick after system start seems to be the problem. I cant reproduce this at all. Sometimes it works, sometimes not. Anybody else seeing this? Im on gentoo with 2.6.28 kernel. Any Ideas?

I don't know anything about the af9015, what kind of device it is, what it is supposed to do, or who wrote the code, except that I just grepped the code for af9015, found it, and it is a USB device. So I am an outside observer. Here is my suspicion of what is wrong:
There was a rather nasty USB bug in 2.6.28 (no suffixes). It hit a lot of USB device drivers. The problem showed itself, pretty much, as you describe. I experienced it, too, with a couple of Gphoto camera drivers that I wrote which had been working ust fine for years and worked again just fine when I patched the kernel. So by extrapolation there is quite likely nothing wrong here, either. Probably, the best thing to do would be either to upgrade to 2.6.28.x or to downgrade to 2.6.27.x. If the problem goes away, good.
