As much as I love to poke at the inner workings of my computer, I’ll admit that until recently, I didn’t give much thought to which version of the Linux kernel my desktop system was running. For most desktop users, this isn’t odd. Compatibility of kernel modules is often critical for servers and production systems, but day-to-day desktop usage doesn’t change much from update to update. Two things motivated me to scrutinize the kernel version more closely: considerations for specific hardware; and a very scary bug recently identified in Ubuntu.
