ext4 is trying to allocate 64 KB of memory, and the allocation is failing. There's enough RAM free, but perhaps it's too fragmented to satisfy the allocation. Since it's a higher-order allocation the kernel doesn't try some of the more drastic measures to free memory. The particular code in question here has a fallback to vmalloc the memory, so in this case the failure doesn't appear to be fatal. I assume the installer keeps going without issues after this happens?
I don't think the specific stack trace seen here is something to be overly concerned about. The fact that the installer is beginning to strain the resources of a system with 512 MB of RAM may be of concern, however. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/959620 Title: ext4 backtrace observed with desktop install CD To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/959620/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
