If the driver is able to detect that the device firmware has come back alive, through user intervention or whatever, should there be a way to "untaint" the kernel? Or would you expect it to remain tainted?
The only way to untaint a kernel is a reboot. A taint just means "something happened to this kernel since it was booted". It's used as a hint, and that's all. I agree with the other comments in this thread. Use devlink health or whatever tool to look further into causes. But from what I see here, this code is "good enough" for a taint. -- Steve
