I really don't think that drm or radeon is guilty. I tried to reproduce
with rc3+ & rc4+ with slub or slab, did more then 20 kexec cycle with
same kernel parameter and no issue.

To confirm that radeon or drm is not to blame can you trigger the issue
by using nomodeset kernel option (your fb rotate option is then
useless). If with nomodeset you can trigger the issue can you then try
to trigger it with KMS enabled and with attached patch (real ugly printk
debuging)

Note that i walked over the drm mode init code and i believe the root
issue is that some code in the kernel do a double idr_remove/destroy
which trigger the idr slub/slab error. It just happen that radeon/drm
is call after the idr double free but is not the one guilty.

Note that i don't understand the idr code much, so my theory can be
completely wrong but attached patch might help to shed some light.

Cheers,
Jerome

Thanks for the debugging patch Jerome.
I couldn't trigger the issue with the »nomodeset« kernel option yet.
But I've triggered it with KMS enabled and your patch applied:

If I had to guess it looks like 0 is getting written back to some
random page by the GPU maybe, it could be that the GPU is in some half
setup state at boot or on a reboot does it happen from a cold boot or
just warm boot or kexec?

Jerome, might be worth checking the ordering for when bus master gets
enabled or if we turn off the writeback producers before writeback is
enabled.

Dave.

Only happened with kexec thus far. Cold boot seems to be fine.

Can you add radeon.no_wb=1 to your kexec kernel paramater an see if
you can reproduce.

Cheers,
Jerome

Also cold boot with radeon.no_wb=1 :)

No, I cannot reproduce the issue with radeon.no_wb=1. (I write this
after 700 successful kexec iterations...)

Ok so it's GPU writeback will do a patch on monday.

Sounds like the GPU is writing to physical memory from the
old mappings.
This can happen to other devices if they aren't completely
disabled - which may not happen since the kexec case probably
avoids some of the hardware resets that occurr diring a normal
reboot.

I remember an ethernet chip writing into its rx ring/buffer
area following a reboot (and reinstall!) when connected
to a quiet lan.
