  • Intel NUC J3455 Linux Kernel freeze slowness 4.4.98 errors


    It looks like this has something to do with APIC but I am not sure.  I have similar CPUs with a different MB and BIOS that work fine on the same type of kernel.  A lot of time the issue is because of the C-step setting in the BIOS. The same thing happened on the 2.6 kernel with Centos 6 but this is a homebrew 4.4 kernel so I am not sure why it is happening when even Centos 7 (3.2) kernel works OK.

  • Intel NUC Lower Power Green Computing Boxes Review/Comparison of J3160 and J3455 Models


    Intel NUC J3455 vs Vorke V1 J3160 Both are excellent units but the J3160 is nicer if you require even lower power usage (6W vs the Intel 10W).  The price is attractive on the Vorke V1 as well.  It's been said that the Intel J3455 NUC has a buggy BIOS and some other issues that require attention. The Intel J3455 is still nice because it has 2 RAM slots but it does get hotter due to lack of fan. The Vorke V1 runs cooler, uses less power an........

    I will start by saying I think I know what caused this boot-time error on Linux Mint but should also apply to Debian and Ubuntu.

    Here is the scenario you or a client have a remote machine that was installed as a standard/default minimal Centos 6.x machine on a single disk with LVM for whatever reason.  Often many people do not know how to install it to a RAID array so it is common to have this problem and why reinstall if you don't need to?  In some cases on a remote system you can't easily reinstall without physical or KVM access.
