Bug Description


On some platforms HID over I2C uses GPIO interrupts instead of directly connected to the IO-APIC. Without ACPI GPIO interrupts support, i2c-hid can not find IRQ when probing the device, and shows the following message:

i2c_hid i2c-SYNA7508:00: Could not register for SYNA7508:00 interrupt, irq = -1, ret = -22
i2c_hid: probe of i2c-SYNA7508:00 failed with error -22

So far we've found this issue on some SKL platforms, and one BSW platform.


There's a fix in mainline v4.1-rc1, which add the support for ACPI GPIO interrupts for i2c-hid module.

1. Boot with 4.1-rc1 kernel and patched 3.19 kernel
2. Both touchscreen should work

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-vivid' to 'verification-done-vivid'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See for documentation how to enable and use -proposed. Thank you!
