We are having a problem with Kernel Panic occurrences when trying to boot from NAND Flash (Samsung K9K8G8UOD, 1GB, 8bit) in conjunction with a DM8168 running Linux. With the same hardware and software in the NAND we have seen some power cycles reuslt in kernel panic and for other power cycles the software boots and runs fine. This behavior has been seen on multiple pieces of hardware. Below are the log files from both a case in which Kernel Panic occurred and a subsequent power cycle case in which software boots and runs fine. I have highlighted and further bolded sections in which the Kernel Panic log and the working fine log differ.
