address. 0x7EC44A14


The kdump kernel boot param
root=/dev/ram0 nmi_watchdog=0 irqpoll maxcpus=1 reset_devices
 memmap=exactmap memmap=640K at 0K memmap=130412K at 16384K elfcorehdr=146796K

With the information  that cp fails at file offset 1989877760 bytes
which maps to physical address  0x7EC44A14 how do I further analyze
the issue.?

Any pointers ?
