 disk cache/inode allocations by ntfs3 kernel module.

(i'd to change e-mail for setting correspoing headers for reply)
I made interesting investigation about the problem and found that if I put in kernel parameters preempt=full and threadirqs, crashing is gone, but corresponding process (git in this case) hangs and starting  consuming CPU (therefore writing files is not happens) and it's impossible to kill it. But system is not crashing and stable in this case, case with full kernel preemption.
