Hi,
I'm getting a fatal trap shortly after boot on an up to date
5.4-STABLE box that had previously run 4.11-STABLE flawlessly. Without
the debugging options in the kernel the box just locks up. For
reference the motherboard is a Abit VH6.
If you need any more details, please let me know.
Regards,
James.
