This is a Fujitsu Amilo M1437G with X700Mobile. Suspended/resumed well with UMS with a 2009 distro, but after upgrading the system to a 2015 Mageia 5 and a KMS only driver, screen is white after suspend. If then I hibernate the system through ssh, screen is ok.
Looks like the sbios does something that KMS does not, is there a way to debug this? I join the reg dumps.
