Hi:

I installed the 4.8 release on a new box with 4GB memory, and found
kernel panic when I tried to write date. But the system run great with
only 2GB memory. Is there any kernel compiling option in the LINT, like
the "high mem" option in Linux?

BTW, we also tried 4.6 release, didn't have this problem but had some
different issues.

The following is the kernel core dump when I tried to generate a 1GB
date set.

#0  0xc0216386 in dumpsys ()
(kgdb) where

Thanks in advance for any clue.
