both patches are queued for 6.14.2: https://lore.kernel.org/all/20250409115934.968141886@linuxfoundation.org/ issue was reported in our community forum: https://forum.proxmox.com/threads/.164497/post-762617 as we have access to a server where we could reproduce the issue (crash+loop, before the system was up[0]) I tested with those 2 a kernel with those 2 patches applied - and the system booted successfully. FWIW: I tried building with the original series as well (containing a removal of some PCI-ids), and it also resolved the issue: https://lore.kernel.org/all/20250203162511.911946-1-Basavaraj.Natikar@amd.com/ [0] before proxmox-boot-cleanup.service (so pinning with --next-boot did not help) Signed-off-by: Stoiko Ivanov <s.ivanov@proxmox.com> Link: https://lore.proxmox.com/20250410130834.1745644-1-s.ivanov@proxmox.com

Subject: [PATCH] dmaengine: ae4dma: Use the MSI count and its corresponding
|
|
IRQ number
|
|
|
|
Instead of using the defined maximum hardware queue, which can lead to
|
|
incorrect values if the counts mismatch, use the exact supported MSI
|
|
count and its corresponding IRQ number.
|
|
|
|
Fixes: 90a30e268d9b ("dmaengine: ae4dma: Add AMD ae4dma controller driver")
