mmc panic

Hello,

I have a Beelink BT3 Pro [1] It worked perfectly under 12.1-RELEASE, but crashes on 12.2-RELEASE and 13.0-RELEASE. Sorry, I haven't a dump core only the screenshot.

The crash occurs after X11 is started (using kde plasma). This computer needs the i915kms driver for display, but I think it is to be excluded [2] because I managed to crash it using the scfb driver.

Thanks.

The drm-kmod issue you linked is not similar at all.
The only similarity is the post-panic garbage from the drm driver, but the actual panics are completely unrelated and, as you noted yourself, are not related to drm either.
