Please press any key to reboot. Rebooting... cpu_reset: Stopping other CPUs when shutdown -h now is used to switch off the system after resuming from ACPI suspend. I've tried to debug this issue but setting break at 'generic_stop_cpus' by using gdb seems to be impossible: cpu_reset: Stopping other CPUs Fatal double fault rip = 0xffffffff803e7cf0 rsp = 0xffffff8000023018 rbp = 0xffffff8000023050 cpuid = 0; apic id = 00 panic: double fault cpuid = 0 KDB: stack backtrace: #0 0xffffffff803dd2be at kdb_backtrace+0x5e #1 0xffffffff803a97d7 at panic+0x187 #2 0xffffffff80645694 at dblfault_handler+0xa4 #3 0xffffffff8062d7ed at Xdblfault+0xad KDB: enter: panic System does not hang when 'Poweroff' button is pressed (except the case when pressing the button is not working, this is why 'shutdown -h now' is used) >How-To-Repeat: - power on - use command 'zzz' or Fn+F1 hotkey to suspend the system - resume - use command 'shutdown -h now' - system hangs with message posted above >Fix: >Release-Note: >Audit-Trail: >Unformatted:
