How Linux handles hardware problems
I usually write about various issues in Windows, because there are so many and so frequent. Hardly do I run across major issues with Linux. Until the one I will mention here, which involves a very rare kernel lockup. As we should all know, kernel lockups in Linux are very rare, and in fact I can easily count the number of instances I've seen it happen over 14 years, and keep it under a total count of 10. They usually happen due to hardware problems, when the kernel can no longer run. Recently, I've seen an 10 year old server running Red Hat Linux 7.1, lock up completely.
