I enabled the setting so you can see charts and summary of data after submission, but for those who missed that or just want a direct link to the spreadsheet, here it is: https://docs.google.com/spreadsheets/d/1PuIkhxbxdE2H7fjbmfWYKBJI_iw8A6W1h-SZnQUXBSI/edit?usp=sharing

Pretty interesting stuff, only 7 responses total so far so sample size way too small to draw conclusions. However, initial notes I find interesting:

- 2 of 7 still have stability issues, one has a >1725 chip (1744). Again, this issue not related to segfault stuff, but good data point that newer steppings still show the behavior.
- The only two responses that aren't using QVL listed memory, are the two having issues still. Both happen to be ECC memory as well. May or not be relevant because these two do not have any RCU tweaks in place.
- Of the 5 who have stable systems, the CPU models vary, the chipsets vary, BIOS and AGESA vary from new to old.
- The only constant from 5 "stable" systems is "CONFIG_RCU_NOCB_CPU=y". Whether C-States was tweaked, or rcu-nocbs, or ASLR, there are mixed responses.
- Good on everyone for testing system/hardware stability!

Thank you to those who shared! Let's get more data!
