I happen to have come across this. I don't have the knowledge to help, but it does sound like this is a kernel issue rather than a problem with the intel-microcode package, so let's reassign it. Otherwise it won't get attention from anyone who might know.
"Critical" importance is probably not correct, but I'll let the kernel team triagers decide that. ** Package changed: intel-microcode (Ubuntu) => linux (Ubuntu) ** Changed in: linux (Ubuntu) Status: Confirmed => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1557989 Title: having btrfs installed as the fs is causing a crash when trying to install the intel-microcode package To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1557989/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
