Boot logs are at: http://arm-soc.lixom.net/bootlogs/misc/v3.16-rc4-360-g1501776 There are still some issues to resolve but this is an improvement so let's pick it up and fix with new patches on top. Some of the new warnings are: [WARN] [ 0.785066] usb@12000000 supply vdd33 not found, using dummy regulator [WARN] [ 0.791071] usb@12000000 supply vdd10 not found, using dummy regulator [WARN] [ 0.998658] usb@12400000 supply vdd33 not found, using dummy regulator [WARN] [ 1.004049] usb@12400000 supply vdd10 not found, using dummy regulator [WARN] [ 1.673277] 10060000.tmu supply vtmu not found, using dummy regulator [WARN] [ 1.685873] 10064000.tmu supply vtmu not found, using dummy regulator [WARN] [ 1.706262] 10068000.tmu supply vtmu not found, using dummy regulator [WARN] [ 1.720076] 1006c000.tmu supply vtmu not found, using dummy regulator [WARN] [ 1.733957] 100a0000.tmu supply vtmu not found, using dummy regulator On snow there is also the below.
