The following github repo has pa= tches that add extra logging, which has proven useful in my attempts to diag= nose the issue: https://github.com/emc2/freebsd (sorry for distributing patc= hes/logs in this way, but the logs are quite big). Also in this repo, there= 's a pciconf, devinfo, and dmesg file. The dmesg file shows the trace from b= ooting a patched kernel in verbose mode then suspending it. There's two main curiosities in the dmesg trace. The first is that the powe= r state of all the vgapci device seems to be 0 as opposed to 3 during resume= , which was causing acpi_set_powerstate_method to skip resetting its power d= uring resume. I tried a simple patch (you can see it in the patch and its e= ffects in the trace), but that didn't seem to work. A second curiosity is t= hat acpi_pwr_switch_consumer only seems to have an effect during resume. The only other real lead I have is that the display doesn't seem to be activ= e in acpi_video. I'm not sure if this is an artifact of the efifb driver. Lastly, I recall looking into vga bios calls from earlier such efforts. I i= magine there's something similar for efifb, but I've been unable to track do= wn where this is happening. Advice or information on that front would be mu= ch appreciated.
