What are some common challenges faced by low level Linux kernel engineers when working on driver development?

Low Level Linux Kernel Engineers often encounter challenges such as debugging hardware-software interactions, ensuring compatibility across different kernel versions, and managing strict timing or resource constraints. Troubleshooting in kernel space can be complex, as errors may lead to system instability or crashes, requiring careful use of debugging tools and techniques. Additionally, collaboration with hardware teams and staying updated with upstream kernel changes are critical to ensure robust and maintainable driver code.
