Hi Nicolas, Sorrry for the delay in handling this bug.
We think this regression is due to the upstream change:
commit 9f40ec84a7976d95c34e7cc070939deb103652b0
Author: Juergen Gross <jgr...@suse.com>
Date: Fri Sep 13 12:05:02 2024 +0200
xen/swiotlb: add alignment check for dma buffers
which was backported to the 6.1-stable series.
To confirm this, please can you test:
1. Is this fixed in the latest released kernel for bookworm (version
6.1.128-1)? If it is, you can stop here.
2. Is this fixed in version 6.1.128-1a~test from
<https://people.debian.org/~benh/packages/linux-xen-regression/>?
(This reverts the above change.)
3. Is this fixed in version 6.1.128-1a~test2, from the same place?
(This adds an upstream fix on top of the above change.)
Note that the test packages above are not signed for use with Secure
Boot.
Ben.
