[ixp1200] Looking for patches or fixes to have a working WBSrvr on Linux fo r IXP 2400

[David Mentre]

Hello,

We are currently having an Intel IXP2400 Development Platform. 

Using only free software available on the web, as well as Intel sources
available on SDK CDs, we have been able to compile a complete cross tool
chain (C only), compile and run the Linux Kernel (2.4.19-rmk7-ds1), and boot
on Intel ramdisk.

We have also successfully (cross-)built medrv.o and WBSrvr for linux with
our tooolchain.

While medrv.o seems to work correctly, we have issues with our home built
WBSrvr:

 1. we are unable to make a Pause in debugging. The WBSrvr binaries found on
various Intel SDK exhibits the same behavior. Breakpoints and Restart are
working correctly. 

    Please find below two logs of WBSrvr with the [1]faulting Pause (notice
err code res=9114) when manually called from workbench and [2]the working
Pause using a breakpoint.

 2. the WBSrvr segfaults if compiled from vanilla sources. Adding some
debugging printf solve the issue, so there is probably a race condition in
thread code of WBSrvr.

Has anybody looked at those issues. Any idea how to fix them?

Many thanks in advance,
Best regards,
david
