7.2.12+deb14-arm64 is affected in the same way, reproduced by just
loading the nf_conntrack module shortly after boot.
After the failure:
nf_conntrack module use count: 0
net.netfilter.nf_conntrack_count: 0
nf_conntrack hashsize: 65536
/proc/sys/kernel/tainted: 128
No nf_nat or xt_* modules were loaded.
This time the fault occurred on CPU 1 rather than CPU 4. The faulting
address is 0xfff8, with x24 again containing 0x10000.
