Yes, the change in the iommu/intel is fishy. Will investigate the
change.

It looks to me (a non-kernel expert) like the driver for the keyboard
and trackpad can't read or write to the device due to the IOMMU not
being set up to allow those reads/writes (e.g.):

Good morning and thank you for looking into this issue!
* https://kernel.ubuntu.com/mainline/v6.12-rc4/ gives me 404 File Not Found
* https://kernel.ubuntu.com/mainline/v6.12/ boots but no trackpad or keyboard
* https://kernel.ubuntu.com/mainline/v6.13-rc1/ boots but no trackpad or
keyboard
-
And it is most likely the trackpad issue is also introduced by the
change of iommu/intel/. After verify the v6.12-rc4, we could bisect the
iommu driver to fix the trackpad issue.

I found why 6.12-rc1/2/3 deosn't boot, this is a fix for this issue (not
booting), so this fix is in -rc4, so please test 6.12-rc4, in theory,
6.12-rc4 could boot.

@Bill
Could you help test https://kernel.ubuntu.com/mainline/v6.12/ and
https://kernel.ubuntu.com/mainline/v6.13-rc1/.
The drivers for this device are spi/spi-pxa2xx*, mfd/intel-lpss* and
input/keyboard/applespi*, I compared 6.11 and 6.12, there is no
significant change (nearly no change at all).
Confirming the same behavior on my MacBookPro14,1:
* 6.14.0-15-generic boots but built-in keyboard and trackpad are dead
* 6.12.0-rc2 does not boot
* 6.12.0-rc3 does not boot (see attached video; looks like a kernel oops in
intel_lpss_pci)
* 6.11 boots with working built-in keyboard and track
Status changed to 'Confirmed' because the bug affects multiple users.

So the regression is introduced between 6.11 and 6.12, we need to narrow
down further, since v6.12-rc1 doesn't boot on your machine, could you
try v6.12-rc2? https://kernel.ubuntu.com/mainline/v6.12-rc2/
If -rc2 still doesn't boot, try -rc3 ...
thx.
