Linux source 6.1.38 with Debian patches

[Franco Martelli <martellif67@gmail.com>]

Hi,

I've trouble with the 6.1.55 kernel version, my system had become 
unstable, I suspect that firefox-esr doesn't work properly with nouveau 
driver or vice-versa.
I've compiled the kernel of the 6.1.38 time ago and I've installed the 
resulting package so now I have the kernel installed but no longer the 
package (I deleted it after installation... big mistake).

The system seems rock solid with 6.1.38 so I'm looking for the Linux 
source packages of the kernel 6.1.38 that is a previous kernel release 
of the current stable distribution (maybe 12.1) does anybody know where 
can I find it?

Thanks in advance, kind regards
