Kernel log buffer - How to refresh it?

[manty kuma]

Dear all,

I have following queries related to kernel log buffer.

1. At the time of panic, many of pr_info prints are not flushed onto serial
console. What can I do to get them(considering making them emerg is not an
option)?

2. Is there a way I can flush the kernel buffer? I mean all the pending
prints, if any, should be copied into kernel ring buffer.

Thank you.

Best Regards,
Manty
