Ilya Murav'jov, thank you for updating your BIOS. Could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily- live/current/ . If the issue remains, please just make a comment to this.
If reproducible, could you also please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.13-rc7 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags removed: bios-outdated-2201 ** Tags added: latest-bios-2201 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1264707 Title: IO limit 1.2 MB/s for 32bit ubuntu Status in “linux” package in Ubuntu: Incomplete Bug description: 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 ^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. Such a speed is not ok, awfully slow. When I run two or more the same dd commands simultaneously, I have 1,2 Mb/s for every process. WORKAROUND: I have no such problems with the same IO stuff when loading Ubuntu Live 13.10 amd64, i.e. dd reports speed >= 400Mb/s for my SSD disk .
