What workaround? And what chromebox?

There seems to be a kernel bug in 4.19 that affects Haswell chromboxes particularly hard. The work around is to edit /flash/syslinux.cfg as assuggested below. If you are really interested, the whole tale of woe played out over pages 315 to 320 or so in this thread.

 ssh root@<ip address>
<enter password, default is 'libreelec'>
mount -o remount,rw /dev/sda1 /flash
nano /flash/syslinux.cfg
<add ' pci=nomsi' after 'quiet'>
<save and quit: CTRL+O CTRL+X>
reboot 

 Cheers. Sorry for sidetracking the thread, but does this only affect haswell chromeboxes or do Broadwell devices need the workaround too?
