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? -- Matt Fleming, Intel Open Source Technology Center -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
