Really interesting read! Would it be possible to submit these changes through GitHub or as a kernel patch? We'd love to see the full context of the changes—the code actually provides such a clear picture of what's happening (even more so than the docs!), so a proper review of the diff would be great.
 
EDIT: Looking at the description, it seems Claude addressed the issue on the Hailo driver side rather than fixing it in the PCIe driver. Personally, I don't think that's the ideal approach, since the BSP PCIe driver appears to be the root cause. If you get a chance to try my patch instead, I'd be interested to hear how it works for you.

I took a second look at the log, I think it's probably due to the enabled eMMC. 
EDIT: I added the emmc part to my A7Z dts, it also crashes... So that's definitely the root cause.
I disable it for A7S in my repo for now, you can compile it yourself with a Linux 6.18 kernel or wait for Nick.
 
By the way A733 eMMC seems to use the same eMMC driver as A523, so probably mainline already supports it.

I think I’ve got KVM enabled, but as they discussed previously, it's not a Linux kernel issue, there's some specific u-boot firmware needed. Since I don't think the open source firmware is ready yet, I guess KVM likely is not feasible on A733 for now.

Hi all,
Over the past few months working on the A7Z, I’ve successfully ported a number of BSP drivers to Linux 6.18.
The code is available here:
https://github.com/alexcaoys/allwinner-bsp/tree/linux-6.18.y
It’s currently tested on 6.18.19 and should, in theory, work with newer 6.18.y releases. I’ve tried to reuse as much upstream (mainline) drivers as possible, and have also upstreamed support for PCK600 and ET7304 used on the A7Z.
Hopefully this helps accelerate ongoing mainline efforts. Feedback, issues, and PRs are very welcome.
I may also look into creating branches for Linux 7.x in the future.
