试试加kernel参数(单独/组合使用):
[list=*]acpi=off 见https://www.kernel.org/doc/Documentation/kernel-parameters.txt:
- acpi= [HW,ACPI,X86]
- Advanced Configuration and Power Interface
- Format: { force | off | strict | noirq | rsdt }
- force -- enable ACPI if default was off
- off -- disable ACPI if default was on
- noirq -- do not use ACPI for IRQ routing
- strict -- Be less tolerant of platforms that are not
- strictly ACPI specification compliant.
- rsdt -- prefer RSDT over (default) XSDT
- copy_dsdt -- copy DSDT to memory
- See also Documentation/power/pm.txt, pci=noacpi

reboot=pci,bios,acpi等,见内核源码arch/x86/kernel/reboot.c:
- reboot=b[ios] | s[mp] | t[riple] | k[bd] | e[fi] [, [w]arm | [c]old] | p[ci]
- warm Don't set the cold reboot flag
- cold Set the cold reboot flag
- bios Reboot by jumping through the BIOS (only for X86_32)
- smp Reboot by executing reset on BSP or other CPU (only for X86_32)
- triple Force a triple fault (init)
- kbd Use the keyboard controller. cold reset (default)
- acpi Use the RESET_REG in the FADT
- efi Use efi reset_system runtime service
- pci Use the so-called "PCI reset register", CF9
- force Avoid anything that could hang.
