sr_recalibrate 2:2 exited with voltages 0x22 0x23

Using an app called OS Monitor, I can look at the message log.
I keep seeing a flood of:
[ERROR]
sr_recalibrate 2:2 exited with voltages 0x22 0x23

I'm using CM 7.0.3 encore Rom (Stable)
darlingrin ext4 CM7 042411 Kernel

I thought this might be due to overclocking to 1.3Ghz, but I turned min and max to 800Mhz and I still see this message.

Can anyone else tell me if they see it in their nook color too?
I think it's happening often enough that it's robbing cpu power.

I also notice that you don't have to actually tap the screen, merely get very very close to it to register a touch. It's not that annoying but slows down typing a bit. I saw something else that mentioned the same error, just wondering if anyone knew anything about it, or if it happens to you.

Here's the only time I've seen it mentioned.
