When compiling the sbs modules into the kernel, the system very often stalls when booting.

Very occasionally however (1-10 boots, completly random if cold boot or reboot) sbs boots normally.

I've started to experience this when building 3.18, but I wouldn't be supprised if this bug is older then that; most/all distro kernels have this as a module.

All works fine with everything built into the kernel (except for sbs/sbshc.

I booted the kernel with the debug flag, but didn't get anything extra on this bit.

Is this a Macbook?

I forgot to mention, but yes, yes it is.
