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.
