Comment 0 for bug 1656489

The following log comes from the installer syslog file. Since at least Dec.16th a message is present in all variants of Ubuntu on startup. Since then, in BIOS mode, all installers have opened in try Ubuntu.

There is no incidence on the installation except for xubuntu. In the Xu installer, the skin is light pink. This bug is not shown in the System Log and belongs to ubiquity.

This is a fresh install of 17.04 on an HP desktop. 20170111 build

Visible message on startup in the installer (all of them):

[Firmware Bug]: CPU0: APIC id mismatch. Firmware: 10 CPUID: 0
[Firmware Bug]: CPU1: APIC id mismatch. Firmware: 11 CPUID: 1
[Firmware Bug]: CPU2: APIC id mismatch. Firmware: 12 CPUID: 2
[Firmware Bug]: CPU3: APIC id mismatch. Firmware: 13 CPUID: 3

As seen from Try Ubuntu : /var/log/syslog

I had never seen this message in Zesty nor in Yakkety before Dec. 16th. This bug is not present in Xenial Xerus. Will be waiting for a correction in Ubiquity. Thanks in advance!
