Re: [ROSE] [AX25] 6.15.10 long term stable kernel oops

[David Ranch <linux-hams@trinnet.net>]

Hey Bernard,

Thanks for posting this issue.  Can you copy/paste in the Oops you're 
seeing?  I did see a recent ROSE issue on 
6.16.0-rc6-next-20250718-syzkaller and I wonder if that could have 
created this issue:

https://groups.google.com/g/syzkaller-bugs/c/0TmBbcJ2PKE

Btw, I would say that posting this to netdev@vger.kernel.org would 
probably be more important than this Debian list since this is most 
likely a kernel issue and not a distro issue per se.
