[dpdk-dev] kernel crash with DPDK 18.11

[Dey, Souvik]

Hi All,
              I am using DPDK 18.11 with linux kernel 4.19.28. I have kni devices created and I can see a crash in the kernel with ipv6/v4 fragmented packets. Does anyone seen this already or is there any fixes/patches available for this .

Snippet of kernel panic

Hi Souvik,

I am also facing this issue on DPDK 17.11.4 but not sure whether it is
because of fragmented traffic or not.

Are you able to get the direction regarding this issue? Can you please
guide.

Thanks,
Chetan Bhasin
