When attempt to hibernate my my system I start getting a bunch of swap read errors after it syncs my drive. I am running on a combination Ramdisk and flash file system. I am only using the drive as a swap to try and test out hibernation (suspend to disk). I am running on a system with an LSI SATA controller and LSI driver is built into the kernel.
Code:
~ # swapon /dev/sda1
~ # swapon -s
Filename Type Size Used Priority
/dev/sda1 partition 4016064 0 -1
~ # echo disk > /sys/power/state
