重启时的一般保护故障

在运行硬件故障测试并随后重新启动后，我在重新启动期间看到一般保护故障。硬件和测试用例没有问题，因为与以前的 RHEL 版本一样运行良好。

可以看到如下调用痕迹

当我们设置 acpi=bios 时，不会报告该问题，但在设置 acpi=bios 后我们会看到不同的问题。

问候， 斯里尼瓦斯

你可以尝试：

        reboot=         [KNL]
                        Format (x86 or x86_64):
                                [w[arm] | c[old] | h[ard] | s[oft] | g[pio]] \
                                [[,]s[mp]#### \
                                [[,]b[ios] | a[cpi] | k[bd] | t[riple] | e[fi] | p[ci]] \
                                [[,]f[orce]
                        Where reboot_mode is one of warm (soft) or cold (hard) or gpio,
                              reboot_type is one of bios, acpi, kbd, triple, efi, or pci,
                              reboot_force is either force or not specified,
                              reboot_cpu is s[mp]#### with #### being the processor
                                        to be used for rebooting.
  • 更新 BIOS 并重置其设置
  • 启动时使用acpi_osi=! acpi_osi="Windows 2009"
