未载入Dell g3-3590 Ubuntu 21.04的NVIDIA驱动程序-470

Question

最近，我的nVIDIA卡在ubuntu21.04停止工作。我注意到恒定的CPU使用和顶部显示调制解调器使用44.5%的CPU在任何时候。

对udevadm monitor的调查反复显示了以下情况：

UDEV  [601.231746] add      /bus/pci/drivers/nvidia-nvswitch (drivers)
UDEV  [601.234197] remove   /bus/pci/drivers/nvidia-nvswitch (drivers)
UDEV  [601.314627] add      /bus/pci/drivers/nvidia (drivers)
UDEV  [601.332429] remove   /bus/pci/drivers/nvidia (drivers)
KERNEL[601.590924] add      /bus/pci/drivers/nvidia-nvswitch (drivers)
KERNEL[601.591569] add      /bus/pci/drivers/nvidia (drivers)
KERNEL[601.591594] remove   /bus/pci/drivers/nvidia (drivers)
KERNEL[601.592254] remove   /bus/pci/drivers/nvidia-nvswitch (drivers)

dmesg揭示了以下情况：

[  942.115453] nvidia-nvlink: Nvlink Core is being initialized, major device number 511
[  942.115458] NVRM: This is a 64-bit BAR mapped above 4GB by the system
               NVRM: BIOS or the Linux kernel, but the PCI bridge
               NVRM: immediately upstream of this GPU does not define
               NVRM: a matching prefetchable memory window.
[  942.116045] NVRM: This may be due to a known Linux kernel bug.  Please
               NVRM: see the README section on 64-bit BARs for additional
               NVRM: information.

[  942.116069] NVRM: The NVIDIA probe routine failed for 1 device(s).
[  942.116070] NVRM: None of the NVIDIA devices were initialized.
[  942.116556] nvidia-nvlink: Unregistered the Nvlink Core, major device number 511

再一次，这重复了一遍。

我真的不知道怎么修理它。GPU在Windows 10中完美无缺地工作。

你找到解决办法了吗？

我觉得这只会影响戴尔的G3 3590，因为我找到的任何解决方案都没有效果。我有完全相同的模型，也有同样的问题。它在Ubuntu20.04上也失败了。我尝试了这么多东西，花了一个多星期的时间尝试各种各样的东西。我发现薄荷19.3适用于450种版本的司机。我猜Ubuntu 19也会。在我看来，它就像一个内核错误，https://ubuntu-bugs.narkive.com/eINzSDzw/bug-1742112-new-nvidia-graphics-card-failed-to-initialized

我真的很想让这件事正常运作。
