BTX loader

[Richard Kojedzinszky]

Dear Freebsd community,

I have a problem. I like freebsd, but i have some strange problems.
I have a machine, freebsd4 has been running on it for 2 years, and it 
worked fine, there was no problem with it. Around 3 months ago, I decided 
to switch to 5.4, try the new features, MAC, pf, and such... But I sadly 
noticed that after 1-2 weeks, the machine just hanged. And I could 
introduce the problem again, with starting a buildworld, and making heavy 
disk load parallel. With this stress test, the bug appeared in 2-3 hours.
I was in a dilemma, whether my hardware went wrong, or the software is 
buggy, and made the tests again and again, and the machine again died.
The hang seemed as the machine answered for ping requests, and tcp 
connections could be made to the server, but it seemed like that no other 
disk io could be made. I thought my power supply went wrong, i replaced 
it, but unfortunately, the bug did not disappear.
Then i switched to freebsd6, and since then, the machine is working fine.
So, it is a bad and good news for me, i trust that my hardware is ok, but 
freebsd5.4 looks like it has bugs.
Of course, the last statement is unbelieveable to me, because in my 
workplace, we also do use freebsd5.4 with no problems.
Maybe, just my hardware+software combination is strange?
Than, I was happy using freebsd6, once I issued make buildworld && make 
installworld. After a reboot, my machine did not boot, the BTX loader 
halted. At that point i was angry a bit, and after hours, i replaced 
freebsd6's loader with freebsd5.4's one, and that works fine.

So, for now my freebsd6 system gets loaded by a loader from 5.4, isnt that 
strange a bit?
Did someone had such experiences with freebsd5 or 6?

Of course, I does not think that my hardware is 100% ok, but the present 
just confirms it.
So does anyone has some ideas, what i did wrong?

thanks in advance,
Kojedzinszky Richard
