Hello everybody
While this can barely qualify as a showstopper bug, it still is a nasty bug. :-(
It looks like BTTV is not properly initialized if machine is turned on and booted into Linux. The card is Hauppauge WinTV PCI. If I boot straight into Linux and launch a TV app (xawtv), I get only noise on the screen. In order to make it work I have to boot into Windows, launch a TV application there and only then to boot into Linux.
I see this bug in both 2.2.0pre5 AND 2.2.0ac1. This bug is NOT present in 2.0.33 with a bttv driver (unfortunately I don't recall its version - I built it about half a year ago)
I compared a number of files in /proc when started "cold" and after rebooting from Windows, yet I wasn't able to find any difference that would point to a reason of such a bug.
Upon loading the bttv module, I get:
i2c: initialized Linux video capture interface: v1.00 bttv0: Brooktree Bt848 (rev 18) bus: 0, devfn: 80, irq: 10, memory: 0xfb800000. PCI: Enabling bus mastering for device 00:50 bttv: 1 Bt8xx card(s) found. bttv0: Hauppauge eeprom: tuner=Philips FM1216 (5) bttv0: model: BT848(Hauppauge old) msp3400: init: chip=MSP3400C-C6
With 2.0.30 I get:
i2c: initialized Linux video capture interface: v0.01 ALPHA i2c: driver registered: msp3400 i2c: driver registered: tuner bttv0: Brooktree Bt848 (rev 18) bus: 0, devfn: 80, irq: 10, memory: 0xfb800000. bttv: 1 Bt848 card(s) found. bttv0: model: HAUPPAUGE i2c: bus registered: bt848-0 msp3400: init: chip=MSP3400C-C6 i2c: device attached: MSP3400C-C6 (addr=0x80, bus=bt848-0, driver=msp3400) i2c: device attached: tuner (addr=0xc2, bus=bt848-0, driver=tuner) bttv: PCI display adapter: Matrox Millennium. bttv: PCI display adapter: Matrox Millennium.
I would be glad to help with finding and eradicating this bug
