Public bug reported:
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.
