kernel config 5.4.15-ks-00023-gd18d22ce8f62
On a server running as a NAT gateway, after upgrade the kernel to 5.4 series,
the system panic immediately after keepalived transfer it to master state.
I did a git bisect on 5.4 release, and the result is:
# first bad commit: [d18d22ce8f62839365c984b1df474d3975ed4eb2] net: Fix packet
reordering caused by GRO and listified RX cooperation
kernel 5.5.0 has no such problem.
See attachment for the kernel config. Following is the message captured from
