Subject: I2C touchpad not working: Lenovo Yoga 700
Date: Tue, 24 Jan 2017 22:53:04 -0700 [thread overview]
Message-ID: <20170125055304.GB6021@miniwade.lan> (raw)
Hello,
I'm not sure this is the correct place to ask...
The touchpad isn't working on a Lenovo Yoga 700 (Fedora 25 4.9.4).
I'm not sure about how to debug this further. The main questionable
item I see in dmesg is:
[ 4.209019] i801_smbus 0000:00:1f.4: can't find IRQ for PCI INT A; please try using pci=biosirq

I have filed a bug here with additional details:
https://bugzilla.redhat.com/show_bug.cgi?id=1415727
Any suggestions of where to go from here?
Thanks,
Wade
