Strange boot-time problem with 0.24/fixes & Mythbuntu 10.04LTS

Hi all,

I'm struggling to 'get my head round' this and I'm hoping that someone
here may be able to suggest what might be happening, though I admit that
the problem is probably not MythTV's "fault" ...

For a long time now my backend system has been stable and working well. It
has two Hauppauge WinTV Nova DVB-S2 PCI cards, Mythbuntu 10.04LTS and
MythTV 0.24/fixes.

Sometime recently (I can't say exactly when) something has changed and it
now fails to start correctly from a reboot.

Whereas previously the firmware on both DVB cards has been loaded at boot
time and MythTV has started correctly, what happens now is that no firmware
is loaded and Myth starts up with no adaptors visible.

To get the 2 cards to load their firmware I have to manually go into
backend setup and select each of the cards. There is then a delay of around
a second before the screen showing the card setup is displayed. All I need
to do is select "Finish" on each card, then exit setup, and from then on
everything behaves normally.

The last time this happened we had a mains power loss at 04:00 and it was
07:40 when I manually intervened to get the backend up & running again

Here are the relevant bits of the syslog from boot time:

May 2 04:02:08 mythbuntu kernel: [ 20.324959] cx88[0]: subsystem:

And here is the firmware correctly loading in response to the 'kick' from
my manually running backend setup and selecting each card...

Firmware upload complete

Prior to this I can't see anything suggesting that the firmware is being
requested.

Once it's up and running again the system runs 100% reliably, and I can't
afford the time (or the loss of WAF) right now to even contemplate a
rebuild or upgrade.
Any clues anyone??

Thanks!
George

I can't be sure if this made it to the list first time round, but if it did
then I've seen no responses and so I guess this is a shameless bump :-o
