Well, I just applied a firmware upgrade from A08 (very first firmware revision of the Dell Latitude E6420) to A25 (released just this year, 27 March 2018).
SOURCE: https://www.dell.com/support/home/us/en/19/drivers/driversdetails?driverId=JP0YK I am yet to see the results of the firmware upgrade. This download was marked: "Urgent" But I think it is leaning on the good side since this addresses: CVE-2017-5715 which says "Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis." SOURCE: https://www.cvedetails.com/cve/CVE-2017-5715/ In other words, Spectre. This Spectre problem is being patched with this firmware. And as of this forum post, I typed this using my laptop keyboard. Thanks. ** CVE added: https://cve.mitre.org/cgi-bin/cvename.cgi?name=2017-5715 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1775016 Title: [Dell Latitude E6420] Ubuntu/Xubuntu 18.04 bug: Keyboard stops working in the middle of typing when running firefox and when running the terminal (sudo su) and similar programs until reboot.
