Like Jeff mentioned, I also saw some illegal instructions on early linaro builds but didn't pursue it at the time. I just did a little digging online and there was some mention of ARM errata causing issues ( https://bugs.launchpad.net/ubuntu/+source/fakeroot/+bug/495536)
Based on, https://github.com/gumstix/Gumstix-Overo-Kernel/blob/master/arch/arm/configs... several of the errata are not set. To be honest, I've not found a description of the errata other than the high-level detail mentioned in the kernel config so I'd love to know which are the correct ones to be setting for the Overo.
For omap34/35xx class hardware definitely turn on CONFIG_ARM_ERRATA_430973=y
When using a mix of arm/thumb application binaries on this core.....
