That's very old indeed, and I believe there were some fairly big differences in packet memory management since then. It would be entirely possible for some memory management bug to be introduced by a vendor patch, for example. i dont use vendor patches. its a old kernel i know and i have some backports on it. i avoided switching to newer kernels due some serious issues under specific conditions on these models (unrelated to qos, but to flash memory access). the drivers are basicly the same as for openwrt and it runes fairly well for all schedulers except for cake here. usually there is also a big in the out of tree version of cake. but i havent found anything while reviewing > > - Jonathan Morton > _______________________________________________ > Cake mailing list > Cake@lists.bufferbloat.net > https://lists.bufferbloat.net/listinfo/cake
