Package: src:linux
Version: 6.5~rc4-1~exp1
Severity: Normal
Dear Debian folks,
Currently, Debian’s Linux kernel does not allow late loading microcode
updates. Although discouraged, there are environments where that is
preferred to rebooting/kexec’ing the system. It’d be great, if you could
enable this.
The option was introduced in Linux 5.19, and backported to Linux
5.15.99. Before the feature was working, but as the config defaults to
no, it no longer does.
$ grep LATE_L /boot/config-6.*
/boot/config-6.4.0-1-amd64:# CONFIG_MICROCODE_LATE_LOADING is not set
/boot/config-6.5.0-0-amd64:# CONFIG_MICROCODE_LATE_LOADING is not set
The reason is, that the commit adding the new option
`CONFIG_MICROCODE_LATE_LOADING`, introduced in Linux with commit
a77a94f86273 (x86/microcode: Default-disable late loading) [1] was
backported to stable release v5.15.99 in commit 6d2b3a31 [2], and the
Linux configuration was not updated.
Kind regards,
Paul

Hi
This bug was filed for a (very) old kernel or the bug is old itself
without resolution. Maybe it was for a feature enablement which nobody
acted on. We are sorry we were not able to timely deal with this issue.
There are many open bugs for the src:linux package and thus we are
closing older bugs where it's unclear if they still occur in newer
versions and are still relevant to the reporter. For an overview see:
https://bugs.debian.org/src:linux .
If you can reproduce your issue with
- the current version in unstable/testing
- the latest kernel from backports
or, if it was a feature addition/wishlist and still consider it
relevant, then:
Please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.
Please try to provide as much fresh details including kernel logs where
relevant. In particular were an issue is coupled with specific hardware we
might ask you to do additional debugging on your side as the owner of the
hardware.
Regards,
Salvatore
