Description Erhard F. 2019-07-31 13:08:17 UTC

This is the QEMU output while working on bug #204375.

This is what probably happens on my G4 DP too while testing bug #204375, but as it does not finish booting I can't get a dmesg:

dmesg (kernel 5.3-rc4 + shadow patch + parallel patch, PowerMac G4 DP)

With KASAN working now on ppc32 (https://patchwork.ozlabs.org/patch/1144756/, https://patchwork.ozlabs.org/patch/1144757/), the dmesg output from real hardware. sda6 and sdb2 are btrfs partitions, though not automatically mounted via /etc/fstab. For better readability I cleared the usb/hiddev lines inbetween the btrfs lines:
