Help me with my suspected kernel panic, please

Thanks Bee. Here's the rest. Does it help?

Unable to gather system configuration information.

Bee, thanks for your continuing help, I really appreciate it.

You'll have to be patient with me, though - not too tech-savvy, I'm afraid.

How do I make sure those drivers you've nominated are "still compatible"?

And as for the scary thing, yes, my Lion is roaring at 10.7.5. So what does that scary message mean?

Bee, where do I find these drivers? I've searched for those filenames, and I can't see them.

I don't use Airfoil any more, so that one can go. The app is long gone, so where is this driver lurking?

Logmein I use occasionally, but I'm confused: I've checked, and the app is the current version. So, again, where is this driver? And how do I check if it is current/compatible?

Ambrosia's Wiretap Pro I use occasionally, too, but again, I've checked and I have the current version of the app, but I don't know how to check this driver.

Steermouse I have on all the time. The app is up to date.

Any ideas, Bee, anyone? I'm at a bit of a loss here.

Thanks, Bee.

I have no Rogue Amoeba apps on my machine. So what's that driver doing there, I wonder?

Anyway, I'm in the middle of a project here and don't fancy doing the combo update right now, but I'll get to it at the weekend and report back.

Thanks again for the help, which is much appreciated.

Raunok, thanks for the suggestion, I've downloaded SMC Fan Control and have set it as you suggested. So far my iMac seems to be running about 39, 40 degress C, so I'll see if it makes any difference.

OK, Bee, I hope you're still watching.

I've now done all you suggested.

I have no Rogue Amoeba apps on my machine at all, although I did notice an old R.O. Helper startup item (with an 'Unknown' next to it), which I've now stopped.

I've applied the 10.7.5 combo update. And then I repaired permissions.

Obviously now I'm crossing my fingers, but is there a way I can see if this has improved anything?

Bee, I hope so, too.I'll let you know what gives.

k5yf, I've checked Console, and a recurring line marked Error goes like this ....

16/02/2013 21:25:09.000 kernel: SMC::smcReadKeyAction ERROR TC0F kSMCBadArgumentError(0x89) fKeyHashTable=0x0x8836800

Does that tell us anything?
