hi all,<br><br>Which is the kernel version of the amazon instance? There was some minnor net issues with incorrect checksum that affected 2.6.18. You can disable the checksum with ethtool<br><br>ethtool -K [intercace] tx off<br>
<br>Try above command and check whether the debug message disappear.<br>Hope it helps,<br>Samuel.<br><br><div class="gmail_quote">On 24 January 2011 09:42, Chandrakant Solanki <span dir="ltr">&lt;<a href="mailto:solanki.chandrakant@gmail.com">solanki.chandrakant@gmail.com</a>&gt;</span> wrote:<br>
