Worked on the geerlingguy/linux repository to enhance boot-time observability and reliability for s390 systems using KASLR. Addressed a kernel-level issue by correcting the calculation of the kernel image’s end address in the startup debugging log, ensuring the memory range occupied by the kernel image is accurately reported during boot. This targeted fix, implemented in C, improved the accuracy of debugging information and reduced the time required to resolve boot-related issues. Demonstrated expertise in debugging, embedded systems, and kernel development, contributing a precise patch that reinforced maintainability and reliability of boot logs for s390 deployments in complex environments.
