The data abort that follows happened because the cpsw driver called device_detach_child() on the phy device that never got attached. I don't know why it failed to read from the PHY, I've never seen a problem like that (but I have BB-White, not Black). I do know that you don't need that patch anymore, because it's patching the ti_mmchs driver, and now (as of a few days ago) BB uses the new sdhci_ti driver. (I forgot to send a heads-up to the list about switching drivers, I'll do that in a minute.) I just updated to r254628 on my BBW and it boots fine. -- Ian
