Bug#782515: linux-image-3.16.0-4-amd64: kernel BUG at /build/linux-oP9w_T/linux-3.16.7-ckt9/net/ipv4/tcp_output.c:878!
Package: src:linux
Version: 3.16.7-ckt9-2
Followup-For: Bug #782515
It's TCP Fastopen. After I disable it with 'echo 0 > /proc/sys/net/ipv4/tcp_fastopen' I can start system (and chrome) normally.
Here's a oops report recorded with netconsole.
