CEPC booting problem : URGENT

I am using a CEPC configuration to test my stream interface driver.
Till yesterday it worked smooth. But now , when i download the os
image using ethernet, after download completed , it hangs . Following
is my platform builder debug window....

Can any one help me find out the solution ??? It is urgent.


The platfomr builder log is,

Downloading '....CEPC\Project\RelDir\X86_Debug\nk.bin' to 'CEPC568'
(..IP.) ...
Done!

A crash at that point almost always indicates an IRQ sharing conflict. You
need to make sure you have configured your BIOS to set up the IRQs for
devices such that the Ethernet card used for download and KITL is NOT
shared. The CEPC BSP is not set up to support shared interrupts for the KTIL
NIC.
