Hello Glauber,
the "freeze" happens during the kernel start up. It goes starting with delays in some points.
as I mentioned, when it prints "Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing enabled"
it takes 90 seconds to print the next message. And then to reach that "serial" message it took already 20 seconds.
And it keeps on freezing at some other points too, after that. I also noticed the mouse cursor in the left bottom
is blinking in a very slow frequency, like every 6 seconds. It really disappears for a while, then returns and stay
for another while and so on.
by the way, I messed up my git tree and I was wondering how could I have it back to the state it was when I started
testing this. this linus' commit was the last one, by then:

right now I am not able to reproduce the _exact_ problem I had when i created this thread, i.e. I can't boot anymore. I tested 2.6.25 and it didn't have any
problems, it booted normally, like my 2.6.24.5 did. Then I tried 2.6.25-git1 and it gave me the delay problem I wrote in this thread about, but then the system panics with
"Unable to mount root fs on unknown-block(8,5)". I tested with 2.6.25-git11 and 2.6.25-git12 and they also gave me problems, including
new ones. The long delay is still there and with git11/12, another panic, now a problem very similar to the one Ingo reported at
http://lkml.org/lkml/2008/4/27/309 (gonna give the patch there a try tomorrow, just found that thread).
can't check it for now, as I can't boot anymore, but hopefully tomorrow I will be able to.
Follows my cpuinfo, in the hope it helps.
thanks,
-sergio
