I see the machine only has 4GB of RAM, so it's possible this is a side-effect of an out-of-memory condition somewhere as kernels with 64K pages need a lot more RAM. > SError Interrupt on CPU3, code 0x00000000be000000 -- SError > Kernel panic - not syncing: Asynchronous SError Interrupt This is an SError from user space, where the 'be' bit is the encoding for SError, and the ISS and ISS2 words are all zero. The CPU enables the 'RAS' extension, so ISS is defined according to [1], but none of the bits are set, so this is 'Uncategorized'. This seems particularly unhelpful from FVP, possibly a bug in the RAS error reporting. > WARNING: CPU: 3 PID: 685 at kernel/sched/core.c:3113 set_task_cpu This again seems unrelated and only happens when it panics the second time.
