Any ideas on what it could be?
Is there a way to recompile the kernel adding more debug?
After digging the net a bit I found that netconsole is my friend
there.
It seems that freezing was due to I/O error on swap partition:

Kernel panic - not syncing: Attempted to kill init!

Well, that may be a feature, not a bug :-)
I hope the problem was this one. The machine seems stable now.
