GT-AXE11000 Stability help needed after NAND replacement (amtm/Scribe setup)

[jr lee]

Hi everyone

First of all, a huge thanks to ColinTaylor for helping me rebuild my mtd10 partition earlier. Thanks to that, my GT-AXE11000 is back to life with a fresh NAND chip (Macronix) and a new 90W PSU.

However, I am struggling with stability when using amtm (Swap and Scribe). The router was rock solid for over 9 days on pure NAND, but once I attach a USB storage for amtm, it eventually crashes and reboots.

Current Setup:

• Storage: Kioxia High Endurance 64GB microSD.
• Connection: An unbranded, cheap 3-in-1 USB-C reader connected via a low-quality generic C-to-A adapter (dollar-store grade).
• Logs: I see FCACHE Duplicate blog errors and occasionally BUG: failure at kernel/irq_work.c or eth Link DOWN logs right before it reboots.

I really want to keep using my Kioxia High Endurance card to protect my new NAND from excessive writes.

My Questions:

1. What is the absolute most stable way to connect a microSD card to the GT-AXE11000 for 24/7 amtmusage?
2. Does the Transcend RDF5 truly solve these "Link DOWN" and kernel panic issues caused by USB/EMI interference?
3. Are there any specific NVRAM or Scribe tweaks (like log flushing intervals) you recommend for a setup that uses a microSD reader?

I want to stop these random reboots and finally enjoy this beast of a router. Any advice on the "Gold Standard" hardware for this specific model would be greatly appreciated!

Thank you!
