问题 I'm trying to understand the details of linux booting on arm architecture. I did lot of search on the internet and understood so far some details although I feel each time I read an article it brings lot of other new terms and this makes things more complex. I do have 2 boards running linux, an olimex 9261 and a beaglebone black. My expertise in embedded systems especially arm is pretty good, but didn't play too much with linux though (except some user space programs and char drivers in

问题 The system is CentOS 6.3. I've compile a new kernel and the resulting rpm installed on a target machine. When booting from the kernel I've receive the error in a title of the question. I've extracted corresponding initramfs and compared output of: modprobe --dump-modversions /path/to/scsi_wait_scan.ko with entries in corresponding /boot/ symvers -*. All symbols checksums fit, including of module_layout . Is there a way to extract symvers from kernel itself? 回答1: I've found the problem. Short

问题 As I understand, initrd is a small image that is loadable in the RAM. It is used to boot a complete kernel with all the loadable modules. As part of the process, we need the vmlinuz kernel image which is a renamed version of bzImage. Is it possible to boot the kernel without creating the initrd image? 回答1: initrd/initramfs is optional and not a requirement. bzImage is the pure kernel image and can be booted directly by the bootloader. However it might be neccesary to execute some tasks
