Another (different) crash log
Just had another crash but the backtrace is different.
This time ksm was enabled (enabled to check if that would have any influence on the issue).
Same reproducing steps:
1. Start two VMs
2. Copy some large amount of data from one to the other
Does this still happen with the latest 2.6.40 kernel update? |
