This time after the merging usb trees: drivers/phy/qualcomm/phy-qcom-usb-hs.o: warning: objtool: file already has .orc_unwind section, skipping make[3]: *** [scripts/Makefile.modfinal:61: drivers/phy/qualcomm/phy-qcom-usb-hs.ko] Error 255 drivers/phy/qualcomm/phy-qcom-usb-hsic.o: warning: objtool: file already has .orc_unwind section, skipping make[3]: *** [scripts/Makefile.modfinal:61: drivers/phy/qualcomm/phy-qcom-usb-hsic.ko] Error 255 I just removed the drivers/phy/qualcomm directory from the object tree and rebuilt. Then got this: drivers/phy/ti/phy-tusb1210.o: warning: objtool: file already has .orc_unwind section, skipping make[3]: *** [/home/sfr/next/next/scripts/Makefile.modfinal:61: drivers/phy/ti/phy-tusb1210.ko] Error 255 So removed the drivers/phy/ti directory and rebuilt and the build succeeded. I assume that something is being left around or reprocessed when it should not be. -- Cheers, Stephen Rothwell
