            Bug ID: 206527
           Summary: Kernel 5.6-rc1 w. CONFIG_VMAP_STACK=y + CONFIG_KASAN=y
                    fails to boot on a PowerMac G4 3,6
           Product: Platform Specific/Hardware
           Version: 2.5
    Kernel Version: 5.6.0-rc1
          Hardware: PPC-32
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: PPC-32
          Assignee: platform_ppc-32@kernel-bugs.osdl.org
          Reporter: erhard_f@mailbox.org
        Regression: No

Created attachment 287361
  --> https://bugzilla.kernel.org/attachment.cgi?id=287361&action=edit
screenshot of stuck boot process

Happens on my G4 DP with kernel 5.6.0-rc1 and KASAN (outline) enabled +
CONFIG_VMAP_STACK enabled. kernel is patched with Christophe's '[v2]
powerpc/32s: Fix DSI and ISI exceptions for CONFIG_VMAP_STACK'
(https://patchwork.ozlabs.org/patch/1237387/)

The kernel loads but booting gets stuck at a stage where the display is
initialized but before kernel dmesg gets show (see screenshot).

The machine boots with either CONFIG_VMAP_STACK=y or CONFIG_KASAN=y enabled but
not with both of them enabled together.

Excellent, with v3 KASAN (outline + inline) now work together with
CONFIG_VMAP_STACK=y!
