I have successfully loaded Linux 6.1 on my Digital Prioris XK 5200 DP box.
The install did not recognise the SMP so I installed the SMP kernel as
shown in Knowledge Base Request 175.
Booting the SMP kernel causes an error:
Unable to handle kernel paging request at virtual address ffffd000
Kernel Panic: Attempted to kill the idle task!
In Swapper task - not syncing

Adding the qualifier noapic to the boot allows the system to boot.
This is a bad hardware/kernel interaction which gets correctly worked around
with the noapic parameter.
