Divide by zero in find_busiest_group/update_sg_lb_stats (on physical hardware)
This is relevant to Lucid 10.04.2, but it seems to affect all 2.6.32 builds (and possibly others). Symptoms are very frustrating divide by zero kernel panics/hangs after roughly 200 days uptime.
Ubuntu 2.6.32-32.62-server 220.127.116.11+drm33.16 -- image package is linux-image-
There appears to be no fix, however, as of 2.6.32-32.77
There have been patches submitted to the linux-ec2 package for this bug, however it also appears to hit some types of physical hardware, and there has been no movement on getting these packages included into the main kernel packages, hence I am opening this bug, as I don't think it will be addressed outside of ec2 as long as the impression is given that it is only an ec2 bug.
Please do not mark this bug as a dupe unless the ec2 ticket is promoted to encompass all kernel builds and patches are submitted to all relevant image packages. The ec2-related ticket does indicate that it is related to the mainline kernel build however it offloads patches to the main kernel tree (which, given that the bug has been open an entire year, may not be immediately forthcoming). It would be nice if the current Lucid packages (as well for other affected releases) would receive the same patch that the linux-ec2 package has received.
Thanks for any assistance possible from the kernel team. =)
