--- Comment #3 from Christophe Leroy (christophe.leroy at csgroup.eu) ---
That might be a consequence of commit 41f20d6db2b6 ("powerpc/irq: Increase
stack_overflow detection limit when KASAN is enabled") which increased the
limit from 2k to 4k for PPC64.

This happens when you get an IRQ while being deep into BTRFS handling it seems.

It should be investigated with BTRFS team why the callstack is so deep.
