System hang with blank screen and also with NMI error. We analyzed the issue and found that the boot process is good even up to the grub stage 2. But as soon as the kernel runs, the EBDA used by the boot code seems to be corrupted, thus resulting NMI/PCI error from the subsequent dma access. Using another kernel 2.6.32-71 works fine and no EBDA got corrupted. EBDA is used by the boot code to store the tx and rx descriptor for used by the adapter fw for dma operation and is assumed to not be changed once boot code is running. Since this is in the linux init code, need help to identify potential issue.
