panic in 3.2.x

I have built a 3.2.0 kernel using the fedora kernel-3.2.0-2.fc17.src.rpm, and a 3.2.1 using kernel-3.2.1-4.fc17.src.rpm. With either of these I get several panics per day on a Lenovo S12 (intel version), but only if I have an SD card in the built in card reader. I am not really sure how to trigger them, but they are frequent enough that I could probably get more info if instructed.

I have not had any panics with 3.1.x kernels

The panics are all different, and I can't spot anything particular in common. Here is a bit of one:

EIP: [<c091de99>] __schedule+0x379/0x8b0 SS ESP: 0060:f400bea0
CR2: 000000000c043777a

Kernel panic - not syncing: Fatal exception in interupt

I boot with nolapic_timer to avoid freezes.

Let me know if there is any other info I can give.
