Thanks Justin! It might take me a couple of days to get some time to build a new kernel and get it tried out on the machine, but I'll give it a go and let you know the results. BTW, there is one typo in what I wrote, the machine is still on 11.0. So the breakage happened somewhere between 11.0 and 11.1. -- Greg On 2020-05-20 08:12, Justin Hibbits wrote: > On Tue, 19 May 2020 21:39:59 -0700 > Greg Lewis <glewis@eyesbeyond.com> wrote: > >> Hi all, >> >> I've seen this on every 11.x release starting with 11.1 (the machine >> is still running 11.1 as a result), but here is the boot failure for >> 11.4-BETA2.
