I am going into: /usr/src/kernels/2.6.18-92.1.10.el5-x86_64 and doing a "make mrproper" attempting to rebuild the Modules.symvers file. As I added ALSA 1.0.17 to the current kernel. I am getting an error: make mrproper scripts/Makefile.clean:17: /usr/src/kernels/2.6.18-92.1.10.el5-x86_64/drivers/infiniband/hw/amso1100/Makefile: No such file or directory make[3]: *** No rule to make target `/usr/src/kernels/2.6.18-92.1.10.el5-x86_64/drivers/infiniband/hw/amso1100/Makefile'. Stop. make[2]: *** [drivers/infiniband/hw/amso1100] Error 2 make[1]: *** [drivers/infiniband] Error 2 make: *** [_clean_drivers] Error 2 Is this not the correct way to rebuild the Modules.symvers file?
