Warning to fellow Strix TRX40-E users who upgraded to BIOS 0902:
I've spent literally the last week banging my head against the wall in Linux. Kernel general protection faults, SMP faults, graphics faults... I've tried Arch, Ubuntu, Fedora... same thing. I've blamed the AMD OpenCL graphics driver, my clocks, all kinds. I've literally spent 10 hours a day on this trying to figure out why I can't run my PC for more than an hour without crashes.
Then I remembered the EFI update... I rolled it back last night and it's still running today without issue. I have 100% CPU usage (BOINC), 95% GPU usage (FaH) and it's rock solid. I'll be emailing ASUS but... well... LOL Asus right? I didn't see any issues under Windows, strangely, so if you're Windows only you'll probably be fine. But I'm posting this for anyone who uses Linux to save you the sleepless nights I've had - just roll back!
