Comment 80 for bug 509180

I just got this issue on an up to date Natty x86_32. Ubuntu crashed totally while i was compiling and after reboot i got Input/output error's on files modified by the build (Makefiles, .o's etc). Modifying files (for example with make) doesn't work, only deleting helps. This bug may cause loss of data, so I'd treat it with high priority.
