Hello Everyone, I wanted to recompile the kernel from source. I downloaded the source rpm (kernel-2.6.9-78.0.1.EL.src.rpm) from centos and installed the rpm. In /usr/src/redhat – I unzipped and untar’d the linuxx-2.6.9 base files. After doing that I wanted to patch the kernel with the numerous patch files that came with the src rpm. The problem that I am having is that a lot of the patch files fail – an example: patch -p1 < ../linux-2.6.9-megaraid-update.patch patching file drivers/scsi/megaraid/mega_common.h Hunk #1 FAILED at 27. 1 out of 1 hunk FAILED -- saving rejects to file drivers/scsi/megaraid/mega_common.h.rej patching file drivers/scsi/megaraid/megaraid_mbox.c Hunk #1 FAILED at 10. Hunk #2 FAILED at 217. Hunk #3 FAILED at 244. Hunk #4 FAILED at 286. Hunk #5 FAILED at 340. Is this not the right procedure for patching the kernel? Any insight would be appreciated. Thanks, Steve
