Hi,all When I'm doing suspend/resume S3 (suspend-to-memory, echo mem > /sys/power/state) on mainline 4.2-rc4, Skylake, I found that , the time cost for resume_console is quite long, It takes nearly 4 seconds to finish. Since there is only one console available in my system(VGA console, by checking /proc/consoles), I think after resuming from S3, VGA writing is very time costy when resume_console is trying to dump all temporary logs to console. I would be appreciate if anyone expert here can give some information on why VGA console takes some much time and would be happy to test with your suggestions, thanks!
