Ilya Murav'jov, thank you for reporting this and helping make Ubuntu better. As per your https://launchpadlibrarian.net/160830243/BootDmesg.txt : [ 0.000000] ACPI BIOS Warning (bug): Optional FADT field Pm2ControlBlock has zero address or length: 0x0000000000000000/0x1 (20130517/tbfadt-603)
Hence, as per http://www.asus.com/Motherboards/M5A99FX_PRO_R20/#support an update is available for your BIOS (2201). If you update to this following https://help.ubuntu.com/community/BiosUpdate , does it change anything? If it doesn't, could you please both specify what happened, and just provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Thank you for your understanding. ** Description changed: - I recently installed a new motherboard Asus M5A99FX PRO R2.0 and found - out that IO speed is very low; i.e. the dd command output: - + I recently installed a new motherboard Asus M5A99FX PRO R2.0 and found out that IO speed is very low; i.e. the dd command output: dd if=/dev/zero of=/tmp/output bs=8k count=1000k - - gives - ^C13885+0 records in 13885+0 records out 113745920 bytes (114 MB) copied, 99.6639 s, 1.1 MB/s This issue is reproducing with my new SSD (with ext4), my USB drives and my hard disk (with ext4) from Ubuntu i386, 13.04 and 13.10.
