Just to confirm:
- you are using an early 2015 11" Air 7,1;
- the drive inside is a PP3-8D256 which looks like a LiteON nvme drive; and
- you upgraded to Mojave from High Sierra using the the PP3-8D256.
Got a tip for us?

You don't want 25 until you solve the panic issue.
Try setting it to 3, restart, log in, close the lid, wait about 5 minutes, open the lid. Hopefully, no panics.
I think it is a bootrom issue. You could try setting hibernate mode to 0.
I found some of my old posts and, after installing the Mojave beta, my early 2015 13" received a bootrom update to MBA71.0178.B00: https://forums.macrumors.com/thread...with-samsung-ssd.2099405/page-5#post-26200791
i had 0 before, tried even 25 just to be sure and still same panic
i gettin Failure code:: 0x00000000 00000014
Have a look at this post to ensure you ran the correct pmset instructions: https://forums.macrumors.com/thread...ssd-to-m-2-nvme.2034976/page-29#post-25703979
yes, after sudo pmset -a hibernatemode 0 i check pmset to se hibernatemode and restarted macbook
the weird thing is, when i close lid for the first time macbook is waking up prety much everytime, but when i try do this for second time i get this panic
There are only things I can think of that could cause the pnics: the drive or old bootrom.
Do you have a log from the kernel panics?
I do

Time Awake Since Boot: 360sDoes the panic appear to be related to the hibernation?
The panics may be related to the bootrom or drive since people in this thread have disabled sleep and stopped the panics.
Ok i will get his nvme ssd next week first and i test this out, 256gb isnt enough for me, next step gonna be changing boot rom to 180
Currently my 2015 MBA bottom is MBA71.0176.B00
Looks like I will try reinstalling GM Mojave
I was not successful in getting my bootrom updated. If I remember correctly you need to have a compatible SSD to use while updating the firmware then you can install the NVMe M.2 drive. When I reformatted my M.2 drive I reinstalled using Mojave OS 14.2 which has firmware update but I am wondering if I need to get my hands on the original Mojave GM install?
It may be that the MBA needs to be running the latest HS or GM Mojave bootrom?

Hi all, thanks for all the awesome info on aftermarket MacBook Air ssd upgrades! Before finding this thread, I upgraded my 11” i5 MBA from the original 128 SanDisk ssd to this WD black ssd https://www.amazon.com/gp/product/B07C9H8MHD/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 using this sintech adapter https://www.amazon.com/gp/product/B07C9H8MHD/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 .
Unfortunately, I experienced shorter battery life and daily kernel panics with the WD drive (doesn’t seem to be related to sleep). So I am looking to return the WD and get a different m.2 NVMe ssd. It seems like the ADATA XPG SX8200 is pretty highly recommended right now, but I’m also considering getting a SM/PM951 off of ebay. Based on some googling I did, it seems the SM/PM uses Samsung’s UBX controller, like the 950 PRO that has worked so well for Macdctr. I believe that this is also the same controller that is used in the Samsung OEM ssds used in some 2015 MBAs. With that in mind I’d love to hear others’ thoughts on which ssd (ADATA or SM/PM951) would we a better buy for battery life and stability.
Thanks in advance!

What's the model # for your 11" MBA?
Although the Samsung drives use the same controller as an original Apple drive, they won't be running Apple firmware so the MBA is going to treat as a nvme drive.
Have you looked at the panic logs to see what was causing these panics?
The MBA would be an early 2015 11". I was asking because panics are not uncommon with non-2015 MBAs and MBPs because of hibernation.
So I looked at the panic logs, but I'm not sure what it means. Here is one of the logs.
Looks like an issue with the nvme drive or driver.
Is the air running the latest bootrom?
