Comment (by lc):
We have a bunch of TL-WDR3600. Some devices have this issue, others don't.
So we thought there must be a difference. We found the difference is the
the RAM used.
Devices having reboot issues is eqipped with Zentel A3R12E40CBF
Devices without reboot issues has SKhynix H5PS5162GFR
Devices without reboot issues has Winbond W9751G6KB-25
It seems SKhynix and Winbond were for older production lots (serial #
starting with 13B, 13C, 2141)
Zentel was used for serial # starting with 2143 and 2145
Can you guys check which RAM you have on your boards? Can you confirm our
findings?
Maybe the hardware gurus know why Zentel RAM chips cause the reboot issue
(timing?) and find a fix.
