stack overflow after boot menu when booting from CD

[Matthias F. Brandstetter]

Hi all,

I have a little problem with FreeBSD 5.2.1 boot CD. After booting from it I 
can see the boot menu and below "error: stack overflow".

The machine is a Pentium 233 MMX with 128mb RAM.
Any ideas on this?

TIA and Greetings, Matthias

PS: I have no problem with a FreeBSD 4.10 CD, but I need 5.x cause of 
ACLs...

PPS: There is allready a bug submitted, but without any fix:
