Description of problem: Since F7, my system's USB is working unstable and very strange: * When I turn on my printer (Canon Pixma iP4000), it is detected. Anyhow when I try to print, sometimes the printer is reported as not being available, sometimes the print request is just consumed but not printed, some other times everything works fine. Whe the printer does not print, I have to reboot the system. Just disconnecting and reconnecting the printer is not sufficient. * My scanner (Canon CanoScan LIDE20) is detected, but when I try to scan with SANE, sometimes SANE shows no error, but seems to scan a black paper. I have to reboot the system several times to get it working again. * Sometimes (especially when I turn on the printer), my USB mouse crashes. Then the mouse pointer position seems to be updated only two times a second. I have to reboot the system to get the mouse working again. Version-Release number of selected component (if applicable): kernel-2.6.21-1.3194.fc7 kernel-2.6.21-1.3228.fc7 How reproducible: Sometimes, when connecting or disconnecting an USB device. No problems occured with USB memory sticks yet, though. Steps to Reproduce: 1. Install F7, use an USB mouse 2. Connect and disconnect USB peripherals (like printers, scanners) 3. Try to use those USB peripherals, watch the mouse pointer Actual results: USB is unstable. Expected results: USB works as stable as it did on FC6. Additional info: I have made a clean F7 installation, no upgrade from FC6. Seemingly independent of the problems, my system sometimes suddenly starts to produce a LOT of those messages in /var/log/message: Jul 4 02:36:00 monique kernel: hub 5-8:1.0: activate --> -110 Jul 4 02:36:00 monique kernel: hub 5-8:1.0: hub_port_status failed (err = -108) Jul 4 02:36:00 monique last message repeated 3 times with the following message repeated about every two seconds until I reboot the system: Jul 4 02:36:02 monique kernel: hub 5-8:1.0: activate --> -108 Jul 4 02:36:02 monique kernel: hub 5-8:1.0: hub_port_status failed (err = -108) Jul 4 02:36:02 monique last message repeated 3 times Before the mouse starts jerking, I am getting this message in /var/log/messages: Jul 4 11:38:10 monique kernel: irq 16: nobody cared (try booting with the "irqpoll" option) Jul 4 11:38:10 monique kernel: [<c0452a3e>] __report_bad_irq+0x36/0x75 Jul 4 11:38:10 monique kernel: [<c0452c1c>] note_interrupt+0x19f/0x1db Jul 4 11:38:10 monique kernel: [<c0566ab3>] usb_hcd_irq+0x21/0x4e Jul 4 11:38:10 monique kernel: [<c045210e>] handle_IRQ_event+0x1a/0x3f Jul 4 11:38:10 monique kernel: [<c04533b1>] handle_fasteoi_irq+0x86/0xa6 Jul 4 11:38:10 monique kernel: [<c045332b>] handle_fasteoi_irq+0x0/0xa6 Jul 4 11:38:10 monique kernel: [<c04072bb>] do_IRQ+0xac/0xd1 Jul 4 11:38:10 monique kernel: [<c0419c45>] smp_apic_timer_interrupt+0x74/0x80 Jul 4 11:38:10 monique kernel: [<c04058ff>] common_interrupt+0x23/0x28 Jul 4 11:38:10 monique kernel: [<c0403d60>] default_idle+0x0/0x3e Jul 4 11:38:10 monique kernel: [<c0403d8c>] default_idle+0x2c/0x3e Jul 4 11:38:10 monique kernel: [<c04033d6>] cpu_idle+0xa3/0xc4 Jul 4 11:38:10 monique kernel: [<c071bb5f>] start_kernel+0x435/0x43d Jul 4 11:38:10 monique kernel: [<c071b25a>] unknown_bootoption+0x0/0x202 Jul 4 11:38:10 monique kernel: ======================= Jul 4 11:38:10 monique kernel: handlers: Jul 4 11:38:10 monique kernel: [<c0566a92>] (usb_hcd_irq+0x0/0x4e) Jul 4 11:38:10 monique last message repeated 4 times Jul 4 11:38:10 monique kernel: Disabling IRQ #16
Try booting with the kernel parameter "usbcore.autosuspend=0" That will be the default in the next kernel release.
Kernel 2.6.21-1.3255 is in testing now with patches to fix this. Please test.
"usbcore.autosuspend=0" really resolved this problem. I haven't had any USB issues since. I don't want try testing kernels on my machine though. Sorry.
Reopening this bug for F8. With kernel-2.6.23.1-49.fc8 and without "usbcore.autosuspend" option, the bug occurs again as described in the opening comment.
Hello, I'm reviewing this bug as part of the kernel bug triage project, an attempt to isolate current bugs in the Fedora kernel. http://fedoraproject.org/wiki/KernelBugTriage I am CC'ing myself to this bug and will try and assist you in resolving it if I can. There hasn't been much activity on this bug for a while. Could you tell me if you are still having problems with the latest kernel? If the problem no longer exists then please close this bug or I'll do so in a few days if there is no additional information lodged.
I still have a problem with 2.6.23.9-85.fc8 even with usbcore.autosuspend=0
That is now "usbcore.autosuspend=-1" in 2.6.22+
Changing it to -1 seems to have fixed by usb.
BTW the smolt info for my system: http://www.smolts.org/show?UUID=810e7126-1c69-4aff-b8b1-9db0fa8aa15a
This message is a reminder that Fedora 8 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 8. 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 '8'. 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 8'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 8 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 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 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.
