更新微碼

我有幾乎最新的英特爾 CPU，我的電腦根本無法關機。dmesg：

啟動iucode_tools說可以更新微碼：

selected microcodes:
 064/001: sig 0x000906e9, pf_mask 0x2a, 2019-10-03, rev 0x00ca, size 100352
 065/001: sig 0x000906ea, pf_mask 0x22, 2019-10-03, rev 0x00ca, size 99328
 066/001: sig 0x000906eb, pf_mask 0x02, 2019-10-03, rev 0x00ca, size 100352
 067/001: sig 0x000906ec, pf_mask 0x22, 2019-10-03, rev 0x00ca, size 99328
 068/001: sig 0x000906ed, pf_mask 0x22, 2019-10-03, rev 0x00ca, size 100352

…但我無法弄清楚如何做到這一點。執行sudo apt-get upgrade intel-microcode根本沒有幫助（進行了升級但沒有任何改變）。

正如 user263096 的評論中已經暗示的那樣，如果您使用 BIOS 啟動，只需使用主機板製造商網站更新您的 BIOS 並安裝最新的 Intel 驅動程序。

即使這不太可能，我也會檢查

/boot/loader/entries/entry.conf

文件如果

initrd  /cpu_manufacturer-ucode.img

在那兒。如果沒有，請添加它。這僅在您使用 uefi 時才有意義。

編輯：如果您使用的是 GRUB，請嘗試

/boot/grub/grub.cfg
