Any ideas why?
are you printing from an interrupt context? use iprint for that. also, are you looking for trace(1)? we ship with a tool for showing scheduler decisions. > > Also I was doing with tail -f /dev/kmesg in the background and without that > /dev/kmesg loses the start of output up to some random moment where it shows > it. Could the problem be that i have too many outputs? that's what tail *does*. It shows the tail (by default, last 10 lines) of the file. ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/T31db04ef89737d25-M5f99acee5813b799ce86afe6 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
