But the adresses seems ok. So it shows you have a 24 Mb text+rodata area. 8 BATs are used (16+8+8+32+64+128+256+256) By increasing CONFIG_DATA_SHIFT to 25, you'll get a 32Mb alignment So you will have only 6 bats used (32+32+64+128+256+256), so two additional data BATs will be available for KASAN. But regardless of the BAT stuff, KASAN should work properly. --=20 You are receiving this mail because: You are watching the assignee of the bug.=
