Hi Shimoda-san,

These values look good and match the values from Falcon.

-EPROBE_DEFER when requesting the DMA channel? This is weird, at first glimpse this seems unrelated to my series. But you say v6.6-rc1 works fine. Strange.

Very kind of you but I think this is not needed. There is a Spider in Kieran's lab and I will try to reproduce the issue there myself. If that doesn't work, I'll come back to you.
Thank you for the report!
All the best,
