freebsd stable - Feb 2009 - 7.1-stable (righ after release) locks up on soekris net5501 every day

Hello, Freebsd-stable.

  I installed 7.1-STABLE on my new Soekris net5501. Kernel config is
in attach.

    This unit lock up in strange way every day. It is pingable, but no
access to host on any network protocol (sshd, named, etc are not
answering), and serial console (only one this unit has) DOESN'T ANSWER
too!

   Only way to un-freeze it is cold reboot.

   I've thought, it is overheating problem (before I discovered, that
it pingable even when console is totally frozen), but now I monitor
temperature, and it never raises over 48C, which is not cold, but
looks Ok...

  I have only serial access to unit from other FreeBSD server,
accessed by ssh, so my access is

  ssh -> FreeBSD server -> cu -> Soekris net5501

 And it seems, that my USB2Serial cable can not generate BREAK. When I
press "~#" in cu it output "~" and doesn't go to
debugger (yse, I have
BREAK_TO_DEBUGGER option)...
