Hello,
I have a Creative WebCam3 and am using it with a Gigabyte GA-71XE which
uses the Advanced Micro Devices [AMD] AMD-756 [Viper] USB chipset.
My problem is I get hard lockups after a short (less than three minutes)
period of time when using my webcam. It's the only USB device connected.
I've tried un/loading the ov511 driver before/after taking a snapshot,
un/loading the videdev on top of that, and un/loading the entire usb stack
on top of that. Each of those events get progressively worse - in other words,
loading the driver once I can get up to 3 mintues whereas unloading the entire
usb stack then reloading it before I want to use the cam I get about 15 seconds.
I've talked to the ov511 author and he's coming out with a new driver soon
which I will test. He's also reported that another person in a similar
situation (ohci + webcam) is having the same problem.
I leave with you my dmesg and an offer to help test anything you can think
of, outside of meddling with code.
Thank you.
