Every time I start my laptop, I get a firmware request from the kernel for /lib/firmware/intel-ucode/06-0f-0b for a microcode update. This fails, and no package provides it, but I would like to know why the kernel is requesting this. As far as I knew, all microcode is located in microcode.dat, and pushed from userspace to kernel using microcode_ctl, rather than the kernel requesting it itself. If I can’t find any explanation, I’ll just block all microcode requests in the client to avoid PackageKit users having searches automatically done for files that aren’t going to exist.
Help appreciated. Thanks.
