Hi, I am seeing occasional issues when using an easycap card on our fedora 17 machine. We are using gstreamer to record video from the device which is using the precanned stk1160 driver. Over extended periods i.e. following a number of video recordings we occasionally see an issue whereby gstreamer suddenly starts to complain and video capture fails. I can see various issues flagged under the system logs but ultimately the only course of action to resolve the issue is to unplug and re-insert the usb easycap device. The system resources all appear to be fine, i.e. lots of RAM, disk space etc. Here are the machine details: Linux localhost.localdomain 3.7.6-102.fc17.i686 #1 SMP Mon Feb 4 17:52:09 UTC 2013 i686 i686 i386 GNU/Linux Easycap device: Bus 002 Device 002: ID 05e1:0408 Syntek Semiconductor Co., Ltd STK1160 Video Capture Device Logs: message log: May 8 10:00:51 localhost kernel: [675741.708919] stk1160: queue_setup: buffer count 8, each 829440 bytes May 8 10:00:51 localhost kernel: [675741.711801] stk1160: setting alternate 5 May 8 10:00:51 localhost kernel: [675741.712947] gst-launch-0.10: page allocation failure: order:6, mode:0x80d0 May 8 10:00:51 localhost kernel: [675741.712952] Pid: 11623, comm: gst-launch-0.10 Tainted: P O 3.7.6-102.fc17.i686 #1 May 8 10:00:51 localhost kernel: [675741.712954] Call Trace: May 8 10:00:51 localhost kernel: [675741.712963] [] warn_alloc_failed+0xad/0xf0 May 8 10:00:51 localhost kernel: [675741.712967] [] __alloc_pages_nodemask+0x55f/0x7d0 May 8 10:00:51 localhost kernel: [675741.712973] [] dma_generic_alloc_coherent+0x8d/0xc0 May 8 10:00:51 localhost kernel: [675741.712976] [] ?
