Package: linux-source-4.19
Version: 4.19.132-1
Severity: important

Hello,

Since linux-image-4.19.0-10-amd64, I'm facing regular Kernel panics - "RIP: 0010:__cgroup_bpf_run_filter_skb+0x26d/0x3d0" - resulting in full (file) *server freeze*.

The issue is pretty well described and summarized in https://forum.proxmox.com/threads/kernel-5-4-44-causes-system-freeze-on-hp-microserver-gen8.72050/page-2#post-323498

The "culprit" commit - "netprio_cgroup: Fix unlimited memory leak of v2 cgroups" - is indeed included in Debian kernel (4.19) since changelog entry 4.19.131-1

It *seems* there is already a patch proposed upstream (although here for kernel 4.9): https://lkml.org/lkml/2020/7/20/883

Best regards,

Cédric
