> The system seems to go into sleep state just fine, it just freezes when waking up again
The behavior differs per device. Some sleep but freeze on wakeup, some immediately wakeup after sleeping, and some (like mine) will go to sleep 98% of the way, but the fans keep spinning. That was a dead giveaway for me that the bug was triggered. I suspect that on some systems, either the fans turn off and the system succeeded to getting to sleep 99% of the way, or the fans are so quiet that people do not notice them. And from that limbo state you can only recover with a hardware shutdown or interrupting power.
I'm fairly certain this issue is fixable for you as well, either with only this fix (and we just have to find the proper port(s), or with this fix and for whatever other device might be causing this issue.
