Package: linux-image-6.6.8-amd64-dbg
Version: 6.6.8-1
Severity: normal

Dear Maintainer,

Thanks for being a Debian volunteer.

In linux-image-6.6.8-amd64-dbg, the symbols for vmlinux are stripped, 
which
defeats the purpose of installing the package.   vmlinux was not 
stripped in the
trixie kernel dbg package:

$ file $(find /usr/lib/debug -name "vmlinux*" -type f)
/usr/lib/debug/boot/vmlinux-6.6.8-amd64:   ELF 64-bit LSB executable, 
x86-64, version 1 (SYSV), statically linked, 
BuildID[sha1]=144f4fcbb5d506514b6552bbd7c7d03fd7ddadde, stripped
/usr/lib/debug/boot/vmlinux-6.5.0-2-amd64: ELF 64-bit LSB executable, 
x86-64, version 1 (SYSV), statically linked, 
BuildID[sha1]=1921e63a5a6fcc611ae79e17f64ec58225ec23eb, with debug_info, 
not stripped

The modules provided with linux-image-6.6.8-amd64-dbg are not stripped:

$ file /usr/lib/debug/lib/modules/6.6.8-amd64/kernel/fs/ext4/ext4.ko
/usr/lib/debug/lib/modules/6.6.8-amd64/kernel/fs/ext4/ext4.ko: ELF 
64-bit LSB relocatable, x86-64, version 1 (SYSV), 
BuildID[sha1]=53e944d5e261d12c3beb55bcdfb85837c34c761b, with debug_info, 
not stripped

Hopefully it is not too much work to fix this minor error.

Thanks,
Alison Chaiken

Unfortunately the linux-image-6.6.9-amd64-dbg package has the same 
problem as 6.6.8:

The fixed version is in experimental, uploaded as 6.7-1~exp1, so the
change is not contained in the most recent unstable version.
