https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D218632 Bug ID: 218632 Summary: Loading of i915kms at boot time breaks cyapa (I2C) Product: Base System Version: CURRENT Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: denis@tambov.ru Created attachment 181760 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D181760&action= =3Dedit it has two dmesg.boot files with and without i915kms module I use 11.0-STABLE on a chromebook. One day I loaded i915kms module at boot = time and touchpad broke. I worked via cyapa driver which uses I2C bus. If I boot the system without i915kms module, which uses I2C too, the cyapa works. Michael Gmelin suggested me to test CURRENT version, unfortunately, the behaviour was the same. The kernel shows me messages: cyapa0: Unable to bring device out of bootstrap cyapa0: Unable to initialize iicbus0: <unknown card> at addr 0xce If 11.0-STABLE booted without i915kms, cyapa works fine, then I start Xorg which loads i915 (kms?) and that all works too. The attachment contains two files /var/run/dmesg.boot with and without i915= kms module. The kernel was booted with -v flag.
