Hi Adam,

Sorrry for the delay in handling this bug.

We think this regression is due to the upstream change:

commit 9f40ec84a7976d95c34e7cc070939deb103652b0
Author: Juergen Gross <jgross@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.

Thank you for testing and confirming the fix.  This fix should be
included in the next update to bookworm.

Ben.
