Random kernel panics in EFI 2.1

[giorgiolongo]

After updating to the 2.0 EFI i keep getting kernel panics. Randomly it starts not responding then after 20-30 seconds of spinning wheel it crashes. Here's my kernel panic log

this also happens when trying to update to 11.2.3, where after loading for a while it crashes and goes back to the current installation of 11.2.1

@giorgioshine Is your install on an external disk plugged-in to thunderbold-usbc port?

[giorgiolongo]

@profzei nope, I bought a Kingston a2000 as a replacement for the pm981. it worked perfectly for a while and just recently I got this kps. I looked into the logs and I think I'm going to try removing nvmefix as it might cause issues with an SSD which should work out of the box. if you have any idea on what's causing the issue let me know. and thanks for the amazing config

[giorgiolongo]

I fixed it by disabling NVMEfix in config.plist

[profzei]

@giorgioshine Thank you for your feedback: I'll add this info in homepage for other users!

[profzei]

@giorgioshine I just found the following in NVMeFix's Changelog for next (April) release:

Added APST workaround for Kingston A2000

If you like, then you could give it one more shot: I'm going to make it available in my next (April) release...

[giorgiolongo]

@profzei oh ok perfect. I'll update as soon as the new release comes out
