Kernel tests on baremetal needed

[John Paul Adrian Glaubitz <glaubitz@physik.fu-berlin.de>]

Hello,

I'm currently debugging another kernel bug which I think affects UltraSPARC III
only. In particular, it can be triggered by reinstalling the openssh-server package
on Debian [1].

The reproducer might be surprising, but the underlying reason is that systemd can
use the BPF functionality of the kernel to provide strengthened security for the
SSH service on Linux and the backtrace shows a crash in "bpf_check()" in the kernel.

I would like to ask anyone to just try reinstalling the openssh-server package on
their baremetal machines:

# apt install openssh-server --reinstall

and watch the kernel console output while doing that.

Please let me know whether you observe crashes or not and what kernel version you tested.

Adrian
