Trying upgrade to 10.0 met the panic: https://www.dropbox.com/s/fxsily501x50vtw/A8eRRRJKbYM.jpg

It's a fanless Celeron 1Ghz box with AGP. Turning AGP off has helped.

>How-To-Repeat:
Boot on a box with AGP
>Fix:
hint.agp.0.disabled=1
hint.agp.1.disabled=1

 A little addition. I have the lines in my dmesg:
 
 ACPI BIOS Error (bug): A valid RSDP was not found (20130823/tbxfroot-223)
 ACPI: Table initialisation failed: AE_NOT_FOUND
 ACPI: Try disabling either ACPI or apic support.

 It looks like agp_generic_attach is trying to create two device nodes
 both named "/dev/agpgart" with no unit numbers.  That's a no-no, which
 is why you're getting EEXIST (errno 17).  As a workaround, try
 disabling merely one of your two AGP devices.  That will probably fix
 the panic.
 
 The next question is: why do you have two AGP devices?
