Hi Sir
We are porting Linux on Netlogics Board . For checking PCI initialisation ,
we are using E1000 driver as loadable module .
While PCI initialisation is working fine with Core zero ( as I am able to
load E1000 driver and ping works fine) but for another core I am facing
"e1000_clean_tx_irq: Detected Tx Unit Hang" problem and ping does not works.
Following logs are seen.

Please share your opinion if we need some address or registers to be
enabled specifically for another core to get this hang problem get resolved.
