dmesg output from intel machine

I am seeing a kernel panic when I start nfsd on OpenWrt running kernel 6.12.19. Using the 6.6.83 kernel is rock solid. I confirmed this on two Mini PCs, both x86/64. The first is an Intel-N150 based machine and the second is an AMD 8845H-based machine.

The attachment is the output logged to dmesg upon starting nfsd and triggering the panic. This is from the Intel-based machine but a similar output is generated on the AMD one.

Please consider adding the following to the 6.12-stable queue:

de71d4e211ed ("nfsd: fix legacy client tracking initialization")

When I apply this to my build of 6.12.19, I no longer experience the bug/nfsd appears fully functional.
