NetBSD fails to install on AlphaServer DS25

[maed%ukr.net@localhost]

Hello everyone!

I have a problem installing NetBSD (tried NetBSD from 5.2 up to 6.01) on HP 
AlphaServer DS 25.
My step-by-step actions:
1. Downloaded NetBSD/alpha ISO from ftp://iso.de.netbsd.org/pub/NetBSD/iso and 
burned it.
2. Typed "boot dqa0" from SRM console to boot from CD.
3. Boot proceeds, and kernel starts to load, but load fails with "kernel stack 
not valid halt" error :(

I Googled about this problem (hoping it was a kind of SRM misconfiguration), 
but no luck :(( .I also noticed that the DS25 is not in "Supported System 
Models" list at http://www.netbsd.org/ports/alpha/ :(((

Is this system supported? Or is there anyone who had successfully installed 
NetBSD (any version) on the DS25??


Best regards,
Maxim.
