Hi there, Some things to try:
1. See what interrupts are most active: (cat /proc/interrupts; sleep 10; cat /proc/interrupts) > interrupts.log and then using the attached awk script, do the following: awk -f dualcore.awk < interrupts.log > irq_delta.log This will give some idea of the most active interrupts on your system. 2. Obtain a log of busy processes using top: top -b -d 10 -n 6 > top.log 3. See overall system activity (I'm interested in the context switches/second) using vmstat : vmstat 1 -n 60 > vmstat.log 4. and attach all these logs to the bug report. Thanks, Colin Note: I'd also like you refer you to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/177895 which discusses some of these points at length. ** Attachment added: "dualcore.awk" http://launchpadlibrarian.net/13300276/dualcore.awk -- Powertop reports huge number of wakeups and drains battery https://bugs.launchpad.net/bugs/145377 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
