[Bug 757242] Re: Memory corruption when inserting usb 3 uas device
Somehow this looks like the same problem i'm having now. I have a 1TB external hard disk drive which has usb3.0 port. many a times, it doesn't detect my hard disk and after plugging it out, the computer freezes due to high cpu usage by rsyslogd and kworker. surfing the net found out that this is caused by the uas module. checked via usb-devices and found that's true. after plugging out the device, rsyslogd writes this in infinite loop: cmd urb submission failed how to disable uas module permanently? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/757242 Title: Memory corruption when inserting usb 3 uas device To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/757242/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 757242] Re: Memory corruption when inserting usb 3 uas device
I belive this was related to the uas driver, which is known to cause issues and because of that was marked as broken and disabled on all stable kernels recently (3.0.57 and onwards, commit fb37ef98015f864d22be223a0e0d93547cd1d4ef). Natty doesn't got the fix as it is already EOL, but Oneiric and later have now the uas driver disabled, so I'm marking this fixed. If you still experience the problem, please set the status back from fix released. ** Changed in: linux (Ubuntu) Status: Incomplete = Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/757242 Title: Memory corruption when inserting usb 3 uas device To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/757242/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 757242] Re: Memory corruption when inserting usb 3 uas device
Update: It works 100% in openSUSE 12.1, but spews these messages constantly: Apr 5 14:51:32 linux-z66y kernel: [ 5399.002383] xhci_hcd :0a:00.0: WARN: Stalled endpoint Apr 5 14:51:34 linux-z66y kernel: [ 5400.537743] xhci_hcd :0a:00.0: WARN: Stalled endpoint Apr 5 14:51:34 linux-z66y kernel: [ 5401.049646] xhci_hcd :0a:00.0: WARN: Stalled endpoint The thing that motivated me to try it was an extreme problem with Ubuntu, where on these specific Iomega USB disks, using rsync to copy from a server to the disks would hang the system completely. With 6 disks at once, it hangs within 10 seconds. Using ionice and nice might make it take a bit longer, but not much longer. With 3 disks (with ionice and nice), it took about 3 hours to hang. So my desktop is now openSUSE. A week ago, I copied a few disks to the server without problems. And 3 weeks ago, I copied 9 2TB disks (not Iomega) simultaneously to the server. Also yesterday I had 9 Iomega disks hooked up, but 4 of the USB ports won't recognize the disks. This also reminds me of a year ago, where I had about 4 of these same Iomega disks hooked up to a Dell Precision (different machine), and tried to copy from disk 1 to 2, and from 3 to 4 at the same time, and then after a while, the USB bus stopped working. So I moved the USB cables to different ports, and it worked again, and failed again eventually. After I ran out of ports and not even the USB mouse worked, I rebooted. Initially I blamed the hardware... but it does the same thing on server hardware with Ubuntu. And now the previously described funny behavior (similar but not same as old behavior) with my new machine, but only with these Iomega disks. And correction: it was natty a few days ago (11.04), but I said it was Ubuntu 10 in my last post. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/757242 Title: Memory corruption when inserting usb 3 uas device To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/757242/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This still happens in kubuntu 11.10, which I just dist upgraded today. (and kubuntu 10.something that I had before today) It does not happen when I plug my USB 2.0 mouse in the USB 3.0 port. It does not happen when I plug in a small port-powered USB 3.0 hard disk into the USB 3.0 port (which I then tested at 70 MB/s). But it happens when I add a big external Iomega Prestige Desktop Hard Drive in. I get lots of general protection faults on various processes (first is usually ata_id process). And when switching tty consoles, it starts rapidly spewing messages like [ 376.00 ] sr 7:0:0:1: sense urb submission failure. And after enough processes crash, it is not possible to switch consoles, because the system panicked. $ uname -a Linux peter 3.0.0-17-generic #30-Ubuntu SMP Thu Mar 8 20:45:39 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux $ cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=11.10 DISTRIB_CODENAME=oneiric DISTRIB_DESCRIPTION=Ubuntu 11.10 I plan to test it on a SuSE or Debian live CD to compare. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/757242 Title: Memory corruption when inserting usb 3 uas device To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/757242/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@Herton, Thanks for your help. At least i am beginning to understand the nature of my issues now. I seem to have several problems with this machine (A brand new laptop with Sandy Bridge, Hybrid Graphics w/Optimus that cannot be disabled from bios) It will take some time and effort to disentangle the symptoms and connect them to their individual causes. I feel like i am one step in that direction, so thanks again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/757242 Title: Memory corruption when inserting usb 3 uas device -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
