From the timestamps it looks like it always happens when large amounts of data come in from rsyncs. These are cronjobs, so I got the time. Question: I just checked "slabtop -o" and found out it outputs exactly nothing, whereas slabtop (without option -o) shows up just like (process) top with lots of lines. Can you clarify why there is no console output at all with option -o ? > Justin, were you using e1000e in your bug report? > > If you have some additional time, it would also be helpful to get a > bisection of when the problem started occurring (it appears to be sometime > between 2.6.29 and 2.6.30). Do you know what version should definitely be not affected? I can check one kernel version per day, can you name a list which versions to check out? -- Regards, Stephan -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
