Well, both failure modes happen with "shutdown" mode as well (the S| freeze with yesterday's git, too), but still not reproducibly. When s2disk is stuck in "Snapshotting system", the system is not completely dead, it echoes line feeds and Ctrl-C at least (as added to #14504). I wonder what you did if the issue was reproducible... Is that totally unapplicable if the problem happens with 10% probability only? Slow, sure, but until I manage to set up an automated testing bench... -- Thanks, Feri. -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
