--- Comment #7 from Erhard F. (erhard_f@mailbox.org) ---Created attachment 301129 --> https://bugzilla.kernel.org/attachment.cgi?id=301129&action=edit kernel .config (5.19-rc1, Outline KASAN + patches, PowerMac G4 DP) Tried to reinvestigate this issue with a KASAN build of v5.19-rc1 but it seems it's not quite there. I applied the 2 patches "powerpc-kasan-Force-thread-size-increase-with-KASAN" and "v2-powerpc-irq-Increase-stack_overflow-detection-limit-when-KASAN-is-enabled" on top of v5.19-rc1 but I get a non-booting kernel. The kernel boots first but gets stuck on a white screen reading "done found display: /pci@f0000000/ATY,AlteracParent@10/ATY,Alterac_B@1, opening..." Kernel with same config but with KFENCE instead of KASAN boots fine (see bug #216095). -- You may reply to this email to add a comment.
