在其他地方发现类似的内核恐慌报告后，现在看来这是 MD 和 XFS 组合的一个错误。Ubuntu 的错误报告已在此处提交 (https://bugs.launchpad.net/ubuntu/+source/mdadm/+bug/1929591），但是没有得到任何回复，所以我可能会放弃并继续前进——备份我的所有数据，格式化驱动器，并用 ZFS 阵列替换它，完全放弃 MD 和 XFS。
更新日期：2021 年 1 月 14 日和 2021 年 6 月 16 日。原始帖子：
我最近将我的 NAS 服务器从旧的 i7-2600K 升级到了 Ryzen 3700X。两个系统都在 7 个 4TB HDD 上使用软件 MD RAID 6，运行 Ubuntu 20.04。MD RAID 按原样传输到全新安装的 Ubuntu。但是，我遇到了一个问题，这个新版本会定期重启，大约每 2-4 天一次。
我在同时构建的新 VM 服务器上遇到了完全相同的问题（使用 5950X 并运行 Proxmox），但通过在 BIOS 中禁用 C 状态并添加到processor.max_cstate=5 rcu_nocbs=0-31内核参数中解决了该问题 - 它目前正常运行时间为 20 天，这让我很兴奋。在这台机器上做同样的事情不是修复该问题。
直到我在 Raspberry Pi 上设置了串行控制台服务器，我才能够捕获内核崩溃文本。它似乎是一个递归内核崩溃，会填满所有崩溃日志，这解释了为什么我设置kdump/的尝试linux-crashdump从未成功，并且总是因内存不足错误而硬锁定。
内核崩溃似乎是 Linux 的 MD 驱动程序的一个错误。但我不知道为什么它没有在我的旧 Intel 硬件上的相同软件上发生。
我尝试了 2 组不同的 RAM（memtest86 报告两组都正常），以及许多 BIOS 版本——没有任何区别。我最初使用的是 Ubuntu 20.04，因为我总是使用 LTS，但决定重新安装 Ubuntu 20.10，以获得稍新的内核版本（5.8），看看是否能解决问题——也是同样的错误。
眼镜：
- 中央处理器：AMD Ryzen 7 3700X
- 主板：华擎 X570 Pro4 ATX
- 尝试了各种 BIOS 版本，包括最新的 3.60 到 2.20
- 内存：GSkill Ripjaws V 32 GB DDR4-3200 F4-3200C16D-32G
- 还使用了较旧的 Mushkin Enhanced Blackline 32GB DDR4-2400
- GPU：Zotac Geforce GTX 1650 OC SFF
- SSD：Inland Premium 1TB M.2
- 硬盘：7 块 Western Digital Red (Plus) 4TB WD40EFRX
这台机器上运行着 Docker，包括 Plex，它使用 Nvidia Docker 扩展和专有的 450.80 驱动程序进行硬件编码 (NVENC)。我不认为 Nvidia 驱动程序对此有影响？

现在每次重启时我都能重现同样的内核崩溃RIP: 0010:slab_free_freelist_hook+0x35/0x120。它们看起来都一模一样。
我现在不知道该怎么办。我有一块替换主板（Gigabyte B550M Aorus Pro）以及一块 LSI 9211-8i，我将把硬盘连接到它。也许这样可以解决问题？软件/BIOS 中还有其他我可以做的事情吗？
更新日期：2021/1/14：
我将 ASRock X570 Pro4 主板换成了 Gigabyte B550M Aorus Pro，并将所有硬盘移到了 LSI 9211-8ik PCIe 卡上。然而，在经过一段看似有希望的正常运行时间后，又出现了类似的内核崩溃 :(
