Years ago (maybe 10) I decided to update Ubuntu on my dev machine. Everything went well, I boot into the new system and start playing around. But after some time the internet connection drops in the middle of apt-get. I am furious, start cursing at my ISP. I reboot the system, and thankfully, the internet is back on. Start installing new packages, and after some time the connection drops again. I was like "seriously???", then reboot again and net was on again. Took me the whole day to figure out that the particular kernel version I updated to made my particular brand of router drop the connection to the ISP after ~15min. Had to downgrade the kernel to make it work again... Fun times :)

10 years ago would have been 5.04 to 5.10. You did very well to only have that one issue to sort out! Thinks are so much better one decade later.

  Ehh, not quite. I was working on a dev server (which was pretty identical to the prod servers), vmhost/kvm/ubuntu 10.04 LTS. One day I'm staging my updates, to make sure they work when I go to prod.. I do my apt-get and reboot into the new kernel.. but- nothing can be mounted. No developers can work either, they depend on that machine.. I'm looking at it and I can mount the drives from busybox after the kernel panics.. No idea what's going on. I'm asking around in #ubuntu on freenode, since googling is getting me nowhere. 'Just reinstall it' they say. 'Sometimes it's better not to know why these things happen' :| I found the issue, some person was smart enough to think lvm2 was called 'lvm' and then initramfs all my previous kernels during the upgrade procedure- so I couldn't boot into old kernels either. Lost a day of dev time (although it was only 3 developers and me)

    Given that we're talking about 10.04 LTS, I imagine this is from a little while ago and you don't have your devs rely in a single server nowdays?

      Was a very small company, they do everything with VPS's now. No more physical hardware to maintain.

  Another story about ubuntu; and this time I'm the idiot; When you're a sysadmin who's only dealt with one type of linux for a long time you forget what the different distro's do.. there really isn't that much, naming conventions/subtle commands etc; But, apt's packages have the nature of 'always run the latest service if upgraded', a notion that does not exist in centos/rhel/fedora/bsd etc; So, apt-get upgrade on our production database server means the server goes away for a while; not 'the packages are available to be used when you restart the service at midnight'* :p oops.
