Description (partial)

Intermittently some interfaces do not come up after reload with the latest SERDES SPICO FW. This is due to the SPICO crashing which prevents the link init from succeeding. The crash is caused when the page swapping required for link training is somehow interrupted and doesn't complete successfully.

This issue can occur during the booting or reload of Nexus 5600/6000 switches. May also be seen during normal runtime. This is seen for 40G ports.
