To fix it I had to fsck.ext3 - which reported/corrected unused/deleted
inode errors relating to that file.
Since make -j4 was involved in this, sounds like a race some where?

Since then I have booted the same machine with latest git 4-5 times
and compiled a few kernels - nothing bad has happened till now.

Will continue to test newer kernels since I still have few days before
I load this machine with useful data.
