Intel's #spectre microcode update causes random reboots on "Broadwell and Haswell CPUs for both client and data center".
@galaxis what a mess. To update or not?
@MrTumnusInfosec Yeah... We have stopped rolling out the microcode update to our VMware hosts - not taking the risk of random reboots over the weekend. Waiting for better info.
My (updated) work laptop had a bluescreen yesterday - haven't seen that with Windows 10 at all, up to now.
#VMware now recommends to not install the current #spectre microcode upates, or at least not let guests make use of the new commands: "At this point, it has been recommended that VMware remove exposure of the speculative-execution mechanism to virtual machines on ESXi hosts using the affected Intel processors until Intel provides new microcode at a later date."
