FRWK16 - Random Crash then Reboots

Community Support

There are essentially 3 different issues that result Random halts or Random reboots. They all create no logs except the S5_RESET_STATUS.
They seem to affect both the FW13 AMD and FW16 AMD.

I have been told by AMD that these can only be resolved by a manufacturer, i..e FW, talking directly with AMD to resolve them. Users cannot help any further with these problems.

The main problem is reproducibility. Laptops can sometimes go for a whole month without a problem and other times it can happen several times a day.

At least the S5_RESET_STATUS proved it was a low level problem and not a device driver problem.

My theories as to the cause of these is one of:

  1. Uncorrected and undetected bit flips. Probably caused by lack of end-to-end ECC.
  2. Bug in the AMD system management software, that runs all the time on the CPU, but is not part of the operating system.
  3. Main-board design fault causing occasional glitches in the power.
  4. Faulty CPU, for this case, a simple replacement mainboard might fix it.

Also note, this problem is not a FW specific problem. Other manufacturer’s laptops have reported similar:
