I've worked through most of the notifications that I've gotten in the fix common problems plugin, this morning I had a notice that stated /var/log is a 100% full and something that was referring to a trace back call? Both these have disappeared after a reboot.
But I can see in the logging an error is just repeating, so I'll have that log fill up quite quickly again. Please see image attached for error.
This is usually caused by a PCIe device, it can be fixed by moving the offending device to a different PCIe slot, updating the bios or adding pci=nommconfto your syslinux.cfg after append initrd=/bzroot, so it would look like:
append initrd=/bzroot pci=nommconf
