Hmmm… I have an Asus router that reboots itself (kernel crashes). When it was new, it was very reliable, then after some firmware updates it became very bad. It was so bad that it was rebooting itself several times a day. The most recent firmware update (last summer) seems to have made it more stable. I still get the same symptoms (null pointer in kernel) but much less often. (Maybe once in 3 months.) When I was googling the symptoms, I was finding the same problems reported in the open source firmware, so I never bothered to try it. I’ve posted here before about my woes, so if you’re interested, you can read here:
