We have reproduced this regression on Surface Pro 3, but are still trying to figure out the root cause. Thanks!

Hi Matt,
Sorry for the regression. Could you please help to provide
more information about the regression, such dmesg, /proc/interrupts
and hardware(PCI) info from good and bad kernels?
Thanks!
Gerry

Regression in v4.2-rc1 caused by hierarchical irqdomain changes
A git bisect just pointed me at commit d32932d02e18 ("x86/irq: Convert
IOAPIC to use hierarchical irqdomain interfaces") as the reason for why
the trackpad on my Dell XPS13 is no longer working with v4.2-rc1.
I'm now seeing the following errors when booting,
[1.615017] i2c_designware INT3433:00: controller timed out
[1.642496] i2c_designware INT3433:00: timeout in disabling adapter
[1.642500] i2c_hid i2c-DLL0665:01: hid_descr_cmd failed
I tried commit d32932d02e18~1, which works, and things definitely break
starting with commit d32932d02e18.
Any suggestions or requests to try and diagnose why the irqdomain
changes broke this i2c controller driver?
