每当机器启动或 GPU 上有负载时，我都会遇到 NVIDIA RTX A6000 的问题。
dmesg 报告AER: buffer overflow in recovery for三个独立的 PCI 地址：
41:00.1 Audio device: NVIDIA Corporation GA102 High Definition Audio Controller (rev a1)
41:00.0 VGA compatible controller: NVIDIA Corporation GA102GL [RTX A6000] (rev a1)
40:01.1 PCI bridge: Advanced Micro Devices, Inc. [AMD] Starship/Matisse GPP Bridge
AER 也报告称这些问题已得到纠正。但他们也指出，snd_hda_intel 0000:41:00.1该问题也对其产生了影响。

测试并尝试解决消息
与供应商合作，我尝试了大量方法来排除该问题。
- 移除 GPU 即可彻底解决该问题。
- 更新了机器中两个 NVME/SSD Western Digital SN850X 的固件。
- 将系统安装到不同的 SSD 型号上，猜测是 WD SN850X 出了问题。
- PNY 已确认没有适用于 A6000 GPU* 的 BIOS 更新，BIOS 已更新。
- Windows 运行似乎没有发现任何特定问题。
- 内核 6.2 已经过测试，确保所有组件均已得到满足。
- 为防止 PCI 通道上的电源切换导致问题，已在 grub 启动菜单中关闭 ASPM。BIOS 中没有针对 GPU 的 ASPM 控制，只有存储。
一名学生在这台机器上运行了一些计算作业，在使用 GPU 时没有报告任何具体问题。此外，Windows 中的 FurMark 和 Ubuntu 中的 GPUburn 似乎运行正常，这似乎表明问题正在得到纠正。
我仍然渴望更好地了解问题所在，以确保此 AER 消息不会影响机器的未来工作，因为它将用于计算。目前还很难判断这是操作系统的软件问题还是卡的硬件问题。
提前致谢！
答案1
这不是一个解决办法，但我设法将 GPU 移至不同的 PCI 插槽，错误不再出现。GPUburn 测试似乎运行正常。
向主板制造商报告该问题，因为这似乎是一些模糊的 PCI 地址问题（ASUS TeK / Pro WS WRX80E-SAGE SE WIFI）
