Question: How can I disallow installing of the package
intel-microcode in the future? With my bad memory, I may try installing it someday, again.
Yesterday, I installed the

Problem: in this laptop's case, it causes a complete system freeze.
Reproducible: Yes, after each boot.
When: Every time the system boots up. More specifically, sometimes at loading
initramfs, more often very soon after login (up to some 5 minutes).
Hardware: not old but not new laptop Lenovo IdeaPad Z50-70, exact model 59-432384.
Note for BIOS upgrade: Since Lenovo provides BIOS upgrades for Windows only, I can't upgrade. The latest BIOS is dated 24 Sep 2015, which is long time ago anyways, Lenovo BIOS download page.
