I'm in the same position. I need a better Uptime SLA. Pretty ******ed Asus hasn't said anything. What did you go with? I'm changing now too

Rolling back to the old firmware didn't help. I still saw CPU cores individually spiking to 99% while RAM climbed to 100%. Went to Beta and I'm 10 minutes in and CPU / RAM acting normal so far

Seeing talk over on Reddit about this potentially being a mass exploit. 

I'm fortunately still in the return window for mine, are there any solid alternatives or should I just downgrade and wait for the patch? 

Did you do a manual upload of the prior firmware version? Looks like the last firmware update was on 5/12 (5 days ago). Current Version : 3.0.0.4.386_47468-g73fe1fe
