Hi Oleg, Here is the issue from your logs: SError Interrupt on CPU0, code 0xbe000000 -- SError SErrors are special signals to notify software of serious hardware errors. Something is going very wrong. Defective hardware is a possibility. Another possibility if software accessing address ranges that it is not supposed to, sometimes it causes SErrors.
