Package: release-notes
The kernel team decided to switch the default kernel for ppc64el (and
with this also ppc64) to 4k page size. This is known to break systems
in some circumstances. We need to document this in the release notes as
well as in the package.
For reference, the NEWS entry in the package:
* From Linux 6.10, the default kernel on ppc64 and ppc64el
architectures uses 4k page size.
After rebooting, you need to re-create all swap files or partitions.
They depend on the page size and will be not longer usable. See
mkswap(8) on how to do that.
Some file systems might be incompatible with the smaller page size.
At least btrfs created with default settings is known to be affected
and they will not work with this kernel any more.
A btrfs file system can be checked with file(1) (use file -s). It
will show:
BTRFS Filesystem sectorsize 65536
If this number is larger then 4096, the file system can not be
mounted with the default kernel anymore.
If you are affected and require the 64k page size of older kernels,
you can install linux-image-powerpc64-64k or
linux-image-powerpc64el-64k packages.
