Description of problem: USB messages flooding host logs when storage device passed to guest. A very short snippet to illustrate the messages and the frequency: Jul 31 14:22:35 bldr-ccm20 kernel: usb 1-4: reset high speed USB device using ehci_hcd and address 3 Jul 31 14:22:35 bldr-ccm20 kernel: scsi246 : SCSI emulation for USB Mass Storage devices Jul 31 14:22:35 bldr-ccm20 kernel: usb 1-4: reset high speed USB device using ehci_hcd and address 3 Jul 31 14:22:35 bldr-ccm20 kernel: scsi247 : SCSI emulation for USB Mass Storage devices Jul 31 14:23:12 bldr-ccm20 kernel: usb 1-4: reset high speed USB device using ehci_hcd and address 3 Jul 31 14:23:12 bldr-ccm20 kernel: scsi248 : SCSI emulation for USB Mass Storage devices Jul 31 14:23:12 bldr-ccm20 kernel: usb 1-4: reset high speed USB device using ehci_hcd and address 3 Jul 31 14:23:12 bldr-ccm20 kernel: scsi249 : SCSI emulation for USB Mass Storage devices Jul 31 14:23:52 bldr-ccm20 kernel: usb 1-4: reset high speed USB device using ehci_hcd and address 3 Jul 31 14:23:52 bldr-ccm20 kernel: scsi250 : SCSI emulation for USB Mass Storage devices Jul 31 14:23:52 bldr-ccm20 kernel: usb 1-4: reset high speed USB device using ehci_hcd and address 3 Jul 31 14:23:53 bldr-ccm20 kernel: scsi251 : SCSI emulation for USB Mass Storage devices Jul 31 14:24:26 bldr-ccm20 kernel: usb 1-4: reset high speed USB device using ehci_hcd and address 3 Jul 31 14:24:26 bldr-ccm20 kernel: scsi252 : SCSI emulation for USB Mass Storage devices Jul 31 14:24:27 bldr-ccm20 kernel: usb 1-4: reset high speed USB device using ehci_hcd and address 3 Jul 31 14:24:27 bldr-ccm20 kernel: scsi253 : SCSI emulation for USB Mass Storage devices Jul 31 14:25:00 bldr-ccm20 kernel: usb 1-4: reset high speed USB device using ehci_hcd and address 3 Jul 31 14:25:00 bldr-ccm20 kernel: scsi254 : SCSI emulation for USB Mass Storage devices Jul 31 14:25:01 bldr-ccm20 kernel: usb 1-4: reset high speed USB device using ehci_hcd and address 3 Jul 31 14:25:01 bldr-ccm20 kernel: scsi255 : SCSI emulation for USB Mass Storage devices Version-Release number of selected component (if applicable): Software versions: qemu-kvm-tools-0.10.5-3.fc11.x86_64 qemu-img-0.10.5-3.fc11.x86_64 qemu-system-x86-0.10.5-3.fc11.x86_64 etherboot-zroms-kvm-5.4.4-16.fc11.noarch qemu-kvm-0.10.5-3.fc11.x86_64 kernel-2.6.29.6-213.fc11.x86_64 qemu-common-0.10.5-3.fc11.x86_64 How reproducible: Every time for me. Steps to Reproduce: 1. launch qemu-kvm and pass a USB key to guest. For example: qemu-kvm -localtime -no-reboot -m 2048 -smp 2 \ -drive file=/images/disk1.img,if=scsi,cache=none,boot=on \ -net nic,vlan=0,macaddr=00:11:22:33:44:55,model=e1000 \ -net tap,vlan=0,ifname=tap3,script=no,downscript=no \ -vnc :8 -cdrom /misc/boot.dsaks.v3.18.iso -boot dc \ -usb -usbdevice host:0951:1626 2. Have guest read/write to USB key. In my case, approximately 400MB were written - taking about 90 minutes to do so. Painfully slow, and I'm guessing the resets have something to do with that. 3. run dmesg on host (or look in syslog files) Actual results: repeated messages from scsi and usb-storage drivers Expected results: Additional info:
Okay, I can reproduce something similar here. No idea yet what the cause is
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
This message is a reminder that Fedora 11 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 11. 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 WONTFIX if it remains open with a Fedora 'version' of '11'. 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 prior to Fedora 11's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 11 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 please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. 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. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 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. Thank you for reporting this bug and we are sorry it could not be fixed.
This bug still occurs in Fedora 14. Having this very issue with an iPod attached.
