Hi Abijjet,
 Here it goes.
The host is a PC running RedHat 7.2 . The ENP-2505 card is in one of the 
PCI slots of the PC.
The OS on the ENP-2505 is linux.
There is no Window NT machine. We are using the .uof file that come 
precompiled along with the SDK CD.
When the script ixstart is run, no errors are reported.
The ports 0 and 1 are attached to microengine 5 ( found this out after 
adding trace statements in resource manager files).
When I do a lsmod the stackAce is shown as initializing.

By "PC is hanging" I mean that I am unable to do any activity. The mouse 
pointer disappears, keyboard freezes etc.
I think this is because of the FULL_DUPLEX option in port configuration 
in the octmac.c file. I changed it to HALF_DUPLEX and I no longer see 
the problem.

When I do a ping I get the trace message
"Ring to microengine full" after sometime.  I am guessing that the 
microcode that de-queues messages from the ring is not running or not 
loaded on the micro engine.
I hope I have  given enough info.
Thanks,
Kamesh.
