Hi!

Here is the dmesg output:

I've attached a mptable output (showing the same flags :)) in my
previous posting. Features contains PAE - anything else that might help?

I've added device acpi and makeoptions NO_MODULES=yes to the custom
kernel (the PAE kernel config didn't work either).

I just downloaded 5.1-REL/amd64 and gave it a try. No way to get that
booting into sysinstall. I'll try to find a snapshot for it.

In the meantime the system is running a recent -current/i386 and
is just damn fast :)

Thanks, Hendrik
