Hello, I tried to reproduce, but unfortunately, it didn't, and the dmesg log as attachment. I had enabled CONFIG_KASAN and CONFIG_SLUB_DEBUG_ON configs. Can you describe the flow of your operation?Nothing fancy. Just boot a baremetal ARM server on linux-next could trigger it. The .config is here.
The important point you're missing, but which the KASAN dump does hint at, is that that is a machine with SBSA generic UARTs booting via ACPI - I know it doesn't do DT at all because I have one too. What matters there is that pl011 binds as a platform driver, *not* an amba driver. Robin.
