https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D238037 --- Comment #7 from J.R. Oldroyd <fbsd@opal.com> --- There may be another bug. After a suspend/resume on a Skylake system, the new ims driver (in phabrica= tor D16698) does not reset properly. Reads fail with the message from the ims driver "no data received". A bus scan using: i2c -f /dev/iic1 -s resets things after which it works ok again. I am trying to figure out if we are still not saving and restoring all need= ed registers on Skylake, or if the problem is that the bus needs some reinitialization. I suspect the latter given that the scan clears things, = but I am mentioning it here too. --=20 You are receiving this mail because: You are the assignee for the bug.=
