Boot block woes

[Chris Cappuccio <chris_(_at_)_empnet_(_dot_)_com>]

Using this kernel config on an i386, pentium 90 with 80 megs of ram, and a
buslogic bt-946c running as isa, I cannot boot with very current
boot-blocks.  The last config that does run on it has BUFCACHEPERCENT=50
and NULLFS and UNION...

On this machine it was dying with vm_map_create_entry: 73 new entries
created which would display 3 times in blue and then the machine would be
far too slow to use.. So I am upping MAX_KMAP..

But now after I have edited this kernel config, to take out some
unnecessary stuff, using current boot blocks (noticed "fixed boot blocks"
on plus.html), I get booting bsd 1234 5678 90000 +[309303 failed(5)

Also with this config, when ever I halt the machine, I get a large display
of info with panic: vref rele .... If I can get these boot blocks working,
I can make a debug kernel to get this down...

Any ideas/info on the boot blocks and failed(5) ?
