FYI, I managed to find a commit that seems to be causing the issue:
8e791f7eba4c ("x86/kprobes: Drop removed INT3 handling code")
It is not clear why, but if I revert it, I can no longer reproduce the issue. I reported the issue to the patch's author and the x86's ML:
https://lore.kernel.org/r/06cb540e-34ff-4dcd-b936-19d4d14378c9@kernel.org
Thank you again for your help.
