Hi, I'm using 4.12.0-rc1 from https://github.com/jwrdegoede/linux-sunxi and got the following weird trace yesterday. Previously I've been getting output similar to https://www.spinics.net/lists/intel-gfx/msg127638.html, some boots on 4.12.0-rc1 I don't get any trace at all.
This is really weird, we are getting the error while we are trying to acquire the wakelock ... ? Or do we need some other lock before we can take the wakelock ? Any input from one of the Intel developers would be appreciated. Regards, Hans
