Hi Guenter,
Thanks for this report. I'm afk this week, i"ll have a look at it in
more détails next week.
But to be sûre, does that Oops match the bisected commit ? Because
pmd_leaf() for e500 doesn't exist yet so pmd_write() shouldnt be
called.
I did validate all my changes with mpc8544 on qemu when i
implemented this séries, using map_hugetlb mm selftest. What test
tool are you using ?
Nothing special; it is just a qemu boot test with various module test
and debug options enabled,
using a root file system generated with buildroot.
I still don't get anything with mpc85xx_defconfig.
Can you tell with debug options you use and which module tests ?

Thanks,
CONFIG_SLUB_DEBUG_ON is what exhibits the problem.
I sent out a patch:
https://patchwork.ozlabs.org/project/linuxppc-dev/patch/1cdaacb391cbd3e0240f0e0faf691202874e9422.1723109462.git.christophe.leroy@xxxxxxxxxx/
With that patch I can successfully boot your config.
Can you give it a test ?
Thanks
Christophe
