This change made it into v6.12-rc1 as 68e599db7a54 ("drm/amdkfd:
Validate user queue buffers"). A Debian user (Dieter Faulbaum,
on Cc)
reported that this change introduced a regression using a gfx803
device
resulting in a HSA exception when e.g. darktable is used. I
didn't even
try to understand the problem, but maybe one of you have an idea
about
the issue?!

Thank you, this patch helps!
Tested with kernel version 6.12.0+
And (for me) the Debian bug report could be closed.
Thanks to all for your help!
