  Hello. 
  Here a too strange bug report. I'm not really sure that it's kernel bug, but tests showing something like that.
  After Ubuntu 12.04 booted up i have too big problems with all data-storage devices. All of them are working too slow. I tested lastest and oldest kernels and all is ok OLNY on 3.2 kernel. I can't use 12.04 with 3.2 kernel because my ethernet card won't work here. I also TRIED ubuntu 13.04 (LiveCD) and results are the same.
  
  Here a simple example test by DD:
  
  Kernel 3.2.37:
  $ dd if=/dev/zero of=/tmp/1
  ^C2694838+0 recieved
  2694838+0 sent
  copied 1379757056 bytes (1,4 GB), 13,2817 sec, 104 MB/c
  
  Kernel 3.9.11:
  $ dd if=/dev/zero of=/tmp/1
  ^C6721+0 recieved
  6721+0 sent
  copied 3441152 bytes (3,4 MB), 12,56 sec, 274 kB/c
  
  ALL storage devices working like that, all are slowest. /tmp is not mounted anywhere (mean it's all by default). But in Windows all is ok. 
  Hardware: 
  Motherboard: GigaByte GA-Z87X-UD3H rev1.0
  Chipset: Intel Z87
  Software: UEFI F3 AMI,  Ubuntu 12.04 (tests from it) 
  
  $ cat /proc/version_signature > version.log
  file doen't exists! O_o
  I attached file logs.7z that contains /proc/version and lspci -vnvn.
