Battery Sometimes Not Detected

I wanted to submit this bug to the Kernel Bugzilla, but it appears to be down.

Anyway, I'm on kernel 3.0, using 64-bit Arch Linux on a Dell Latitude E6410. Every now and then, the battery shows up as though it's not connected, even while running on it. This is seemingly random, and if it happens, I just reboot my laptop and it will see the battery fine most of the time. I want to say about one in ten boots it doesn't see the battery on average. I filed this first against KDE, but then the problem happened in XCE so it's not a KDE issue. Then, I filed it against upower but they told me this is a kernel bug.

An interesting point to note is that while this problem happens whether I am using my docking station or not, if I undock my laptop while the laptop doesn't see the battery, all of a sudden the battery is recognized.

Running "ls /sys/class/power_supply/" while suffering from this bug gives me:
