Re: latest netdev net-next kernel panic
What is weird - changed in bios and enabled p-states and no panic from 30 minutes w 00:38:07 up 33 min, 2 users, load average: 0.10, 0.13, 0.17 USER TTY LOGIN@ IDLE JCPU PCPU WHAT So the problem can be related to some cpu weird stuff with c/p states or it is random.

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.
