I was not aware setting it to a custom value. I thought 13 is the default on ppc32 which gets overriden to 14 if I select KASAN? But I'll make sure I'll double check this on future builds. Only advanced option I did set is CONFIG_LOWMEM_SIZE=3D0x28000000 (see bug #215389). --=20 You may reply to this email to add a comment.
