If yes, do they show the "illegal instruction" panic at the same address/instruction? Corrupted firmware should show the same panic each time the issue occurs (because the false change to the stored firmware would remain at the same firmware address). > The router is rated only to +45°C but that is the recommended limit for > flash memory, and the room temperature has been up towards 40°C. which > doesn't leave a great deal of margin for router internal heat production. > My query is whether anyone else has seen issues with flash memory in the > recent hear wave. If the logs show illegal instructions at differing addresses that points towards some borderline component (which may still be the flash) that exceeds the systems ability to compensate when the temp is this high. Other possibilities could be the CPU itself may, above a certian temp, simply become flakey. Depending upon what specific CPU the CPU may be the warmest, or second warmest, component in the entire system and with a 40C room temperature it may be operating at a point where it randomly glitches. It could also be something as mundane as a power supply capicator that has partly dried out, and at the higher ambient operating temperature it is allowing more ripple to pass through to the DC rails, resulting in occasional random corruption of data somewhere due to that ripple. > Surely phones get hotter than this? It is possible that phones may use higher temp rated components.
