Thanks Robert. Do you know of any references for these errata beyond just the kernel config. descriptions?
Sorry, Ash I don't have any more references beyond the kernel config... I only know when ubuntu made the switch to "armv7-a + thumb2" (with lucid) my beagle (omap3530 ES3.0 r1p3 based core..) would randomly spout out "Illegal instruction" as seen in (1) and that ARM_ERRATA_430973 has fixed it ever since... I can guess if your in a pure "arm" or "thumb2" environment you'd never run into the issue..
