Hi Daniel, Hi Sergey, I observed the same call-trace since next-20190712 with i195-gfx. First thought this is a problem with clang-9/ld-lld-9, but turned out to be a different objtool problem. The same call-trace I saw with gcc-8 from Debian/buster. This is with clang-9 (prerelease) and ld.bfd (I switched the linker). My kernel-log and dmesg-log are attached. If you need more informations or already have a fix baked up, please let me know. Thanks.
