Dear Red Hat, I *must* use flash drives as part of my business. Writing to a USB Flash drive is E-X-C-R-U-C-I-A-T-I-N-G-L-Y SLOW. The following is reproducible with Fedora Core 23 x64 and Scientific Linux 7.2 x64 with Kanguru SS3 32 GB flash drives https://www.kanguru.com/storage-accessories/kanguru-ss3.shtml Interface: USB 3.0 (Maintains Compatibility with USB 2.0) Data Transfer Rate Max Read: 410MB/sec Max Write: 320MB/sec Yesterday, I was doing a transfer of 20 GB to one of these sticks from Fedora Core 23. After two hours, I shut it down. Then I used my eSata port on my FC23 machine to do a direct transfer to the target machine's hard drive. It took about two minutes. Then, after reconnecting the target machine's hard drive and booting into Windows 7 Pro OEM x64 Service Pack 1, I tried the same transfer. It took about five minutes. Please fix this as soon as possible. I will post to RHEL too. Many thanks, -T
If this helps, this is the hardware involved: SL7: Supermicro X8SAX motherboard http://www.supermicro.com/products/motherboard/Xeon3000/X58/X8SAX.cfm Intel X58 Express Chipset http://ark.intel.com/products/36785 USB3 add on card: Star Tech PCIUSB3S22 https://www.startech.com/Cards-Adapters/USB-3.0/Cards/2-Port-PCI-SuperSpeed-USB-3-Adapter-Card-with-SATA-Power~PCIUSB3S22 Chipset: NEC uPD720202 FC23: Supermicro MBD-C7Z87 (Note: six native bootable USB3 ports) https://www.supermicro.com/products/motherboard/Core/Z87/C7Z87.cfm Intel Z87 Express Chipset http://ark.intel.com/products/75013
Upgraded my Z87 machine from FC23 to FC24 Beta. No symptom change. Copied a 7.4 GB file to an NTFS stick, after four hours, it had only copied 2.8 GB and I had to shut it down.
If it helps with the troubleshooting, "dd" is not slow writing to a flash drive
They have a kernel patch to test over on RHEL 7: https://bugzilla.redhat.com/show_bug.cgi?id=1333582
*********** MASS BUG UPDATE ************** We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 23 kernel bugs. Fedora 23 has now been rebased to 4.7.4-100.fc23. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 24 or 25, and are still experiencing this issue, please change the version to Fedora 24 or 25. If you experience different issues, please open a new bug report for those.
It is not fixed in uname -r 4.7.4-200.fc24.x86_64 WARNING: if anyone does a mass update to test this, it will also update Wine and you will run afoul of https://bugs.winehq.org/show_bug.cgi?id=41273 Which will kill your ability to copy into the clipboard for most of your Wine application. And dnf downgrade has its issues: https://bugzilla.redhat.com/show_bug.cgi?id=1197531
This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '23'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 23 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Would you please add this to Fedora 25 as well?
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
