Bug#1149525: Also affects 7.2.12

Cross-posted to 2 groups.

Show all headers | View raw

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.
