Comment 6 for bug 1932548

OK Kai-chuan, bad news. I got a 1:1 with Tony and... the freeze is still
there, as present as ever. :(

Please let me know how I can help. If you have the iperf command that would
be useful, please let me know (and if I have to use it during a meeting
when it freezes).

Best Regards,

Steve
