Kernel: Crash when generating coredump

How does funding with Polar work?

Backer

Why does "Fund on completion" require GitHub login?

When is the invoice due for "Fund on completion"?

What happens if the issue is never completed?

Do I get any extra benefits by funding?

Do I get progress updates?

Contributor

Do I get a reward?

Is rewards guaranteed?

Maintainer

How can I get funding like this for my open source initiatives?
