What is IONVMeController ?

I have had a couple different Kernel Panics and it from the report that this might be a reason why.

I already had someone at the Apple Store look at the computer and they reset it and it was working fine for about a month without a kernel panic and now the kernel panics have begun again.

Is anyone else with a MacBook experiencing a lot of Kernel panics? I'm a normal user (daily in Mail, Chrome, Safari and a couple other apps but not much heavy duty usage).
