Here’s a little story, or anecdote, if you would..
The laptop I’m using has a wireless card somehow having compatibility problems with Linux distributions, mainly because its maker, Broadcom, only recently made a driver exclusively for Linux. So there I was, using the newly released driver on my current kernel of Fedora, happy as it is working really smooth.
Then I updated to a new kernel, as the software update suggested. I updated, and then restarted tha laptop to complete the installation. Being a routine, I always immediately remove the previous kernel once a new kernel is installed.
And then I booted up the new kernel. Yay I was, as it booted up nicely, or so I thought. The wireless card did not activate, as my wireless suddenly turned of, and I can’t turn it on again. I thought maybe a simple restart would solve the problem, so I postponed my old kernel removal routine and restarted the laptop first.
And voila, the new kernel could not boot up, and the wireless card was the only thing that could not activate. I tried booting up my previous kernel, and at least that worked.
So I thought to myself: “good thing I didn’t remove the old kernel.. whooo!”
Of course, experts in Linux could, maybe recompile the kernel, or something, but me not being someone that good on Linux, would only resort to pulling my hair out and screaming “why won’t you boot up ******* kernel?!” At least my old kernel saved me.
So here’s a good lesson for me and for those with the same routines as mine:
Keep an old kernel to save you in times when your new kernel screws up.
