There were some fixes in the memory compaction code that went into the 3.2.x kernels. Have you seen this with the 3.2.7 or newer kernel updates? I haven't seen this for a while ... and I think it disappeared before I got 3.2.7. |

It usually works, but recently I have seen it fail like this a couple of times. (I would also expect this trace to have a structure that made it clear if it was an oops or what was going on, and some markup that abrt could use for catching it.) kernel-PAE-3.1.6-1.fc16.i686 General ================================= UUID: 494ea71a-dd35-44ee-8a87-555fe820fcab OS: Fedora release 16 (Verne) Default run level: Unknown Language: en_US.UTF-8 Platform: i686 BogoMIPS: 3724.78 CPU Vendor: GenuineIntel CPU Model: Intel(R) Pentium(R) M processor 1.86GHz CPU Stepping: 8 CPU Family: 6 CPU Model Num: 13 Number of CPUs: 1 CPU Speed: 1867 System Memory: 2013 System Swap: 1919 Vendor: Dell Inc.
