  I think the problem is libc6_2.7-6, as explained in #463808, since it
  does not hangs always at the same point, but it always hangs when
  starting configuring packages (so, when running all sort of programs
  that use libc6.
 
 Maybe this should be reassigned then.

Right, I have planned to install etch on a different SGI O2 machine,
then only update libc6 (and maybe locales), to check if this show the
problem.

Bye,
Giuseppe

What are the symtoms exactly? Looking at the bug report I only see notes
about a kernel crash. I fail to see how is it related to libc6.

You are right, but from the stack frame it seems a pointer was shifted
up by 32 bits, and may be the problem.

Well there may be a bug in the glibc causing a problem with the stack
frame, but anyway the fact that you can crash a kernel from userland is
a bug in the kernel, and even a security bug as it is basically a local DoS.

 More information is available at
 http://www.linux-mips.org/archives/linux-mips/2008-02/msg00011.html

From the kernel dump, it looks like the crash occurs in kernel mode (bit
KX of the CP0 Status enabled). A bad address from userland should kill
the process with a SIGBUS.
