In this file I had to comment out:
/* case IOMMU_CAP_DEFERRED_FLUSH: */
With this self compiled kernel the problem is not there.
This file was from 6.5.
Now I took this one:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drivers/iommu/intel/iommu.c?h=v6.4.11
and compiled and installed the kernel. The problem did not occur. The
debian patches were not applied here for my test.
I guess that iommu.c patches in
https://sources.debian.org/patches/linux/6.4.11-1/
cause the problems I discovered.
I would appreciate further advice and guidance.
