Alan, In v3.9-rc3, I find that "reboot" and "shutdown" hang on Tegra. I bisected it to commit 6402c79 "USB: EHCI: work around silicon bug in Intel's EHCI controllers", and confirmed that running v3.9-rc3 with just that one patch reverted does solve the problem. Do you have any idea what the problem might be, or is there anything I can do to help debug this? Thanks. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
