Some odd console errors

[LuKreme]

Noticed this after a reboot (caused by Nambu, but that's another story).

09-Nov-09 08:53:31 com.apple.kextcache[194] InternalModemSupport.kext  
does not declare a kernel dependency; using com.apple.kernel.6.0.

First off, why do I have an InternalModemSupport.kext on my MacPro  
with no modem anywhere and can I get rid of it? Second, what is trying  
to access the nonexistent modem? Third, is this a problem at all?

Reality is a curve.
That's not the problem. The problem is that there isn't as much as  
there should be. According to some of the more mystical texts in the  
stacks of the library of Unseen University - (...) - at least nine-
tenths of all the original reality ever created lies outside the  
multiverse, and since the multiverse by definition includes absolutely  
everything that is anything, this puts a bit of a strain on things. --

Mac OS X installs software for all supported machines on every Mac,  
so you can swap a drive from one Mac to another without a headache.  
There are many dozens of unused kexts on your platter.

Likely, nothing. The message above doesn't indicate any access to any  
modem, but a missing feature in that kext.

> Third, is this a problem at all?

No.

That kext is included with the OS regardless of hardware you install the OS
onto.

Likely nothing is trying to access a modem. You simply have a device "nub"
in the system that is triggering a match of the kext and that kext is being
loaded far enough to do a device probe to see if the kext should claim the
device. While attempting to load the kext the kext loader notes that the
dependencies for the kext aren't fully correct.

Third, is this a problem at all?


No not a problem. Just an oversight on Apple's part of updating the
dependency information in the kext. ...or it is an old kext from an older
version of the OS that wasn't removed on an upgrade.

You can use kextstat and/or ioreg at the command line to see what kexts are
loaded, etc.
