First of all run disk utility and check permissions to see if this clears up your problem.

Otherwise ascertain if "kextcache" is indeed the problem. Run the find command and set the search to search everywhere. Then add to the search parameters to include hidden items. Write down where the files are located since they are in a hidden directory removing "kextcache" may cause further problems. Then create a new folder to move "kextcache" to then restart and see if the problem persists. If it does or new problems develop return "kextcache" to its original location. Otherwise just archive it with stuffit.

Before removing "kextcache" which after looking at Apple technical documents may be very important try this.

Go to /System/Library/Extensions and delete iPodDriver.kext the extension may be damaged and deleting it works for clearing up some other iPod problems.

Removing kextcache would most likely be very bad. From the kextcache(8) man page description:

The kextcache program creates or updates kext caches, which are used to
speed up kext loading operations and to prepare kexts for inclusion in
such media as device ROM.

There are three kinds of kext cache. The first is the mkext cache, which
contains the info dictionaries and binary files for an arbitrary set of
kexts. Mkext caches are used during early system startup to load drivers
essential to mounting the root filesystem and providing basic hardware
services.
I'm no Mac OS expert, but not being able to mount the root filesystem on a UNIX-like OS is a very, VERY bad thing...
