Package: linux-image-amd64
Version: 6.12.16-1
Severity: normal

Dear Maintainer,

I'm not 100 % sure this is caused by the Kernel, but I'm convinced like 99 %. For about 
two weeks I have issues with the networking on several of my servers, mainly with 
mounting NFS shares. Mounting them works only on the servers that are on Debian Stable, 
but the ones on Testing, and thus running 6.12.x, have issues. I've now tried out to 
switch every server running Testing and failing to mount their NFS share to the 6.13.4 
Kernel found in experimental, and for now it looks like this has fixed the issue. Though 
I couldn't update it on one server running as a VM on a Xen hypervisor. When trying to 
boot 6.13.4 on it, I can see in "xl console" this message:


Loading Linux 6.13-amd64 ...
error: not xen image.
Loading initial ramdisk ...
error: you need to load the kernel first.


so I need to select one of the installed 6.12.x Kernels. After successfull 
boot, the first two messages that come up in the journal with priority warning 
or higher are


Feb 24 13:01:18 kernel: Cannot find an available gap in the 32-bit address range
Feb 24 13:01:18 kernel: PCI devices with unassigned 32-bit BARs may not work!


I'm not sure what these two lines refer to, so no idea if that's in any way 
related or completely separate. But beyond that, I don't see any anything on 
any of the servers that I was able to update, that was in the logs before the 
update, but not afterwards. So sadly, right now I can't really help with what 
has changed in one of the 6.12.x versions that seems to have been fixed in 
6.13. But it would be great if whatever the fix is could be backported to 6.12.
