--- Comment #8 from Christophe Leroy (christophe.leroy@csgroup.eu) ---
Looking closer, in fact that might be a false positive.

The huge difference with that bad commit is that:
- Before the commit, the kernel is built _without_ CONFIG_VMAP_STACK
- After the commit, the kernel is built _with_ CONFIG_VMAP_STACK

Would you be able to perform following tests:
- Disable VMAP_STACK and see if the problem still occurs.
- Disable ADB_PMU and see it the problem still occurs.

With the version which preceeds the bad commit, can you disable ADB_PMU and
enable VMAP_STACK and see what happens ?
