Subject: Re: latest netdev net-next kernel panic

Hi Eric


today upgraded some host from 4.13.0-rc7+ to latest net-next from git

and run some tests simulate clients traffic 40Gbit / 5Mpps mixed tcp + udp

There is also bgpd running that feeds FIB with full bgp feed - about 
700k prefixes (so routing tables is about 700k routes with about 300 
nexthops)


There is also simulated about 1000 ip neigh hosts (arp) with about 300 
ip interfaces assigned on vlans



With kernel 4.13.0-rc7+ (git from 05.09.2017) all tests are good 
(besides that there is panic after about 10 hours - every time same like 
in this link:

https://bugzilla.kernel.org/attachment.cgi?id=258257

But looks like acpi related or c/p states with new intel cpus... dono now.
