Hi, Mr. Gregory,

I am sorry to have to explain that I have studied the netconsole and ATM I do not have
the logistics required to implement such infrastructure. Notably, not the hw.

It would be impractical and unsafe to send kernel printk logs from an Ideapad 3 to our
syslog-enabled server over the WAN.

I will let you know if I have any more findings. The NULL pointer dereference was not
deterministic and it is not happening every time I run the kselftest.

I guess we are out of luck, unless you have something that we could implement on our
premises.

Best regards,
Mirsad
