gspca "scheduling while atomic" crash
I have the following device:
Bus 007 Device 002: ID 0c45:60fc Microdia PC Camera with Mic (SN9C105)
Whether I build 2.6.27-rc1 or merge the stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-next.git into my Intrepid kernel (2.6.26), the system will lock up when I try to get video from my webcam.
To see the kernel output, I do this in the console:
mplayer -ao aa -tv device=v4l2:width=640:height=480:fps=30 tv://
The result is a rapid stream of two alternating messages:
BUG: scheduling while atomic: swapper/0/0x8001???? (didn't get it all)
bad: scheduling from the idle thread!
During this the system doesn't respond to anything. It's a Core2 Duo running 64-bit Ubuntu Intrepid with 4GB of RAM. What other info should I provide to investigate this problem?

Hello Brian,
I think I saw the problem: usb_control_msg() is called at interrupt level..
I hope to have a patch this morning.
Cheers.
