I just enabled suspend in system menu. It does not help. System tries to suspend and comes back on. For me it WAS working a month ago very nicely. I do not remember doing anything strange on my system other than updating. Actually I had put it away for about 10 days and used a Nokia since I had a problem with the twin sim card and was trying to see if the twin sim was working after extending use of its twin in Nokia.
The only thing I know it changed is that I swapped the sim with Nokia, since there was a problem with the primary sim in L5 as described here
But this can not be the problem since it fails to suspend even with all HKS in off position.
