+/usr/gnu/bin/gdb:
+       This is the gdb from the ports area (if installed), also known as
+       gdb-4.11.  There is a problem using gdb-4.11 to debug a core-file
+       generated by a binary which uses shared libraries. The problem is
+       basically due to the fact that the shared libraries are mmap'ed at
+       addresses in the memory space of the binary which are not accessible
+       to gdb-4.11 at the time that it tries to examine the core-file. This
+       usually manifests itself in "Cannot access memory at address <foo>"
+       messages at startup and "#0  <bar> in end ()" when you try to do
+       a backtrace ("bt").
+
+       Workaround: start gdb-4.11 without reference to the core-file,
+       e.g. "gdb fubar". Set a breakpoint in main and run the inferior
+       so that gdb-4.11 can resolve references to the shared libraries.
+       After this, use the "core-file" command to force gdb-4.11 to
+       load the core-file, e.g. "core-file fubar.core". Since all
+       shared library references were previously resolved gdb-4.11 can
+       now access the shared libraries and things like "bt" now work.
+       You will also be able to reference items previously on the stack
+       (from the core file), but all globals will show up as zero'd.
+       All these problems may be avoided if you compile the application
+       with -static.

-       DO NOT ATTEMPT TO REBUILD THE BOOT BLOCKS.  There is currently
-       a problem in that the boot block code has grown and if you build
-       it with the new version of as and install them you will NOT BE
-       ABLE TO BOOT YOUR SYSTEM.  This problem will be fixed before
-       the 1.1 release is ship, and should only exist with the 1.1 BETA
-       release.

-       The boot block binaries shipped with the 1.1 BETA release were
-       built using an older version of as and can be installed safely.

-       This will be fixed by the 1.1 release date.
+       Workaround: Try a "ifconfig ep0 down" and a "ifconfig ep0 up"
+       to get it running again.
