Version-Release number of selected component (if applicable):
This happened twice when running big compilation loads so far.
Steps to Reproduce:
1. Update the LibreOffice source from git
2. Run nice -n19 make
3. Let it happen
(I didn't re-test it)
Kernel version: kernel-3.5.0-2.fc17.x86_64
this sounds like a hardware problem of some kind.
That is possible. But it hasn't happened in other kernels...
Is this still happening with 3.5.3? If so, can you boot into the last 3.4 kernel and see if it reproduces there?
