Re: [edk2] [PATCH] NetworkPkg: Fix RSOD issue in Ip6Dxe
Gary,
Can you make a detail description about the issue? Forgive my ignorance, I
don't know 'RSOD' exactly mean here.

Here, you mentioned press POST hotkey between the below line, I'm also confused
with such hotkey, what does the 'below line' mean? Is that your platform
particular implementation for such a hotkey?

Looks so strange for the re-dispatch issue, are you sure it's the same
DelayNode? More description/background for the system configuration or your
analysis is appreciated.
Thanks,

Hi Ting,
This issue can be reproduce by switching POST hotkey quickly and repeatedly.

Hi Gary,
Do you mind sharing more details about how to reproduce this issue? We are not
clear why this would happen.
It seems the code should continue executing the previous
Ip6NdFasterTimerTicking function rather than dispatching the new timer event.
Thanks,
Ye Ting

Hi Gary,
Do you mind sharing more details about how to reproduce this issue? We are not
clear why this would happen.
It seems the code should continue executing the previous
Ip6NdFasterTimerTicking function rather than dispatching the new timer event.
Thanks,
Ye Ting
