Summary0009749: Shutdown hangs on bpf_trampoline_put kernel bug on 6.19.14
Description

My hardware: MSI GP62 6QF
Kernel version: 6.19.14+kali-amd64
The key log lines from journalctl:

bpf_trampoline_put.part.0+0xa8/0x100
bpf_tracing_link_release+0x27/0x40
ftrace_free_filter+0xb2/0xc0

That it affects both 6.16 and 6.19 kernels
That the hang occurs after Syncing filesystems and block devices

You shall report this to the devs of the kernel at their bugtracker, not to Kali (they are stating regularly here they can't debug/help with kernel issues) :-)

"Resolved after upgrading systemd from 259 to 260.1. The bpf-restrict-fs LSM BPF program in systemd 259 was attaching a tracing link that triggered a bug in ftrace_free_filter during shutdown. systemd 260 detects when the kernel BPF LSM hook is not enabled and skips it, preventing the hang. No kernel patch needed."

Either way, always something to report to devs of the software and not to packaging team like Kali :-p
