Pandaboard NIC driver drops connections when under heavy load. This is a workaround fix to resolve the issue.
 
<nowiki>#</nowiki> The driver smsc95xx, used by both Beagleboard XM and Pandaboard uses <br>
<nowiki>#</nowiki> turbo mode by default, that enables multiple frames per Rx transaction,<br>
<nowiki>#</nowiki> increasing performance but consuming more kernel memory.<br>
<nowiki>#</nowiki> To avoid page allocation failures and smsc kevent drops we need to <br>
<nowiki>#</nowiki> increase the minimum free system memory in the kernel to a higher value. <br>
<nowiki>#</nowiki> If you’re still having page allocation failures, try to increase this <br>
<nowiki>#</nowiki> value to 12288 or even higher. You could also disable the driver’s turbo <br>
<nowiki>#</nowiki> mode, but decreasing the ethernet performance. <br>
<nowiki>#</nowiki> If you encounter problems due to the settings please file a bug <br>
<nowiki>#</nowiki> against the jasper-initramfs ubuntu package. <br>
<nowiki>#</nowiki> For more details please check http://bugs.launchpad.net/bugs/746137 <br>
