FreeBSD won't start after shutdown

[Andrey Mishustin]

Hi,

I have an AlphaServer DS10L (SRM version 6.3) and FreeBSD
4.9-PRERELEASE.
With auto_action set to BOOT it boots fine after power on, but it fails
to reboot (with 'shutdown -r now' or 'reboot') or to boot with 'boot'
SRM command after halt (shutdown -h now).

Fails as follows - SRM reads bootblock from dka0 and then says:
Can't open file

Maybe kernel sends some wrong data to SRM on shutdown ? How could I fix
it ?
