This happens when you request URB_SHORT_NOT_OK for an output URB. That's not allowed but it was never allowed and the code in question hasn't changed since 2008. According to the trace it comes from user space: Jun 19 07:14:32 Gull kernel: [41897.036875] [<ffffffffa0081987>] usb_submit_urb.part.6+0x1d7/0x5b0 [usbcore] Jun 19 07:14:32 Gull kernel: [41897.036906] [<ffffffffa008d8ac>] proc_do_submiturb+0xcac/0xd00 [usbcore] Jun 19 07:14:32 Gull kernel: [41897.036954] [<ffffffffa008de48>] usbdev_do_ioctl+0x548/0x1060 [usbcore] Jun 19 07:14:32 Gull kernel: [41897.037000] [<ffffffffa008e97a>] usbdev_ioctl+0xa/0x10 [usbcore] Jun 19 07:14:32 Gull kernel: [41897.037036] [<ffffffff811b72af>] do_vfs_ioctl+0x2cf/0x4b0 Jun 19 07:14:32 Gull kernel: [41897.037046] [<ffffffff811b7511>] SyS_ioctl+0x81/0xa0 Jun 19 07:14:32 Gull kernel: [41897.037051] [<ffffffff815c30ed>] system_call_fastpath+0x1a/0x1f Can you please check what this EMT-3 task is? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

But usbfs allows you to specify it even for output. As the API for usbfs cannot be altered for this reason, the best option is to silently correct the nonsensical option. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
