Kernel 5.19-rc4 runs fine with outline KASAN as long as '# CONFIG_SMP is not set'. It runs perfetly well without any advanced options needed, also setti= ng THREAD_SHIFT manually to 14 is not needed. As soon as I set CONFIG_SMP=3Dy in the attached .config I get a non-working kernel. It boots but gets stuck very early on a white screen reading "done found display: /pci@f0000000/ATY,AlteracParent@10/ATY,Alterac_B@1, opening.= .." Interesting thing is that without SMP I also didn't get memory corruption a= s in bug #215389 nor stack overflows as in bug #216041 after hours of building so far. --=20 You may reply to this email to add a comment.
