I'll write up something later tonight, if/when I have time.  (I usually only 
have time for about 1 properly researched email answer per day.)

The only thing a user can do immediately, for a red-screen cx23418, is unload 
the cx18 driver and reload the cx18 driver.  (My *speculation*, for when the 
red screen happens, is that the cx25843 core is not operating due to some race 
between the cx23418 and cx18 driver when initializing.  I *speculate* it is due 
to intermittent system latencies or transient PCI bus conditions.  I truly do 
not understand the mechanism, as I have only ever encoutered the problem once 
myself in 4(?) years or so of doing this.) 

Note that if cx18-alsa is loaded, cx18-alsa has to be unloaded first. 
Pulse-audio makes that a PITA, because it holds the device open and respawns 
when killed.

Regards,
Andy
