do you see my dmesg kernel command line "memmap=1M!5M ramoops.mem_size=1048576
ramoops.ecc=1 ramoops.mem_address=0x00500000 ramoops.console_size=16384
ramoops.ftrace_size=16384 ramoops.pmsg_size=16384 ramoops.record_size=32768".

if kernel panic reboot, can get /sys/fs/pstore/console-ramoops-0 and
/sys/fs/pstore/pmsg-ramoops-0.
but when resume failed, have to press power button force shutdown, no anything.
