               Could be that the card isn't getting enough juice on the
        new
               board,
               but I'm not really sure. Don't suppose you have a 3rd
        machine
               you could
               try it in, or the ability to try it on the old backend
        with the
               newer
               code to help narrow down if its a hardware compatibility
        issue
               or a
               code compatibility issue? Somewhere or another, I have a
        PVR-500
               of my
               own at home, I should dig it out and throw it in a
        machine...
        
               I'd also advise filing a bug in Red Hat's bugzilla,
        cc'ing me,
               and I can
               get the upstream ivtv maintainer involved, if need be.
        
        Jarod,
        I'll try the F14 x86_64 Live CD on my old backend and see what
        ivtv
        says.  Depending on that outcome, I'll log a bugzilla, etc.
        
        Has anyone else got a PVR-500 working in a MSI P55-GD65
        motherboard?

        Comparing your dmesg with mine Fedora 14 x86_64 ASUS M4A77TD
        Quad AMD
        
        I'm noticing that in your pasebin file between
        line 3 and line 4 Mine is slightly different.
        
        [   68.775816] ivtv: Start initialization, version 1.4.1
        [   68.789429] ivtv0: Initializing card 0
        [   68.802791] ivtv0: Autodetected Hauppauge card (cx23416
        based)
        [   68.816578]   alloc irq_desc for 21 on node 0
        [   68.816580]   alloc kstat_irqs on node 0
        [   68.816586] ivtv 0000:05:06.0: PCI INT A -> GSI 21 (level,
        low) -> IRQ 21
        
        
        I've got the extra lines with the alloc irq part. Don't know if
        this means anything.

Andrew, Jarod,

The PVR500 works fine with the F14 x86_64 Live CD on my old backend
which was running CentOS 5.

The ivtv-related output from dmesg is here:
http://pastebin.com/NZhzPUyK


The start of the differences is where the old backend boots and says
it's changing the "unreasonably low" latency timer from 32 to 64.  On my
new Core i5-based backend, it says the following:

tveeprom 4-0050: Huh, no eeprom present (err=-6)?
tveeprom 4-0050: Encountered bad packet header [a8]. Corrupt or not a
Hauppauge eeprom.
ivtv0: Invalid EEPROM
cx25840 4-0044: Unable to detect h/w, assuming cx23887

The system power supply should be sufficient.  It's a Seasonic 80+ Gold
certified 650W power supply.  I've got everything stuffed in a
Silverstone LC17 case (6 hard drives), which means I only have 1 PCI
slot where I can physically put the cards.  The other PCI slots are
useless for larger cards because the hard drives protrude so far back on
top of the motherboard.

Um, noticed that on your old machine, like mine....

ivtv: Start initialization, version 1.4.1
and you new machine is using a different version

ivtv: Start initialization, version 1.4.2

Don't know it that means anything. I'm no expert at this level.
