[Bug 392204] Re: Huge CPU usage by mount.ntfs process

[Fyodor Kupchik]

Bug present in 2012.1.15AR.1-1ubuntu1. Torrent eats the whole core of my CPU.
Attached the strace for driver. The only thing that, I guess,  triggered high load was the file decompression in windows system. Some error were fixed by chkdisk as well.

** Attachment added: "output of strace -p PID -ff"
