(erhard_f@mailbox.org) --- Thanks for the hint! But adding KASAN_SANITIZE :=3D n to lib/mpi/Makefile d= id not make a change in this case. However I had the idea to disable btrfs (at all) and boot from my other ext4 partition. This worked out and I got further. After other stacktraces flyin= g by the boot process now stalls at offb switching over to radeondrmfb. Again re= boot after timer kicks in after 10min. Seems btrfs is not in the best condition on ppc32 with 4K pagesize.. I would test this on the G5 or Talos II too, but there is no kernel option = to enable 'KASAN: runtime memory debugging' on ppc64. --=20 You are receiving this mail because: You are watching the assignee of the bug.=
