Hi, I've been using qc-usb 0.6.2 fine with kernel 2.6.10 and below. When using 0.6.3 with kernel 2.6.11 or 2.6.12 I get kernel panic when some app (such as xawtv or even testquickcam) tries to use the webcam. I think the problem is in qc-memory.c, more precisely in remap_pfn_range function, because if I use 0.6.2 and replace remap_page_range with io_remap_page_range, the driver loads ok, although I don't get any image. Any idea why I'm getting a kernel panic with 0.6.3?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

Hello,
have the same kernel panic trouble with kernel 2.6.13 and qc-usb 0.6.3. Any news about this?
Thanx, Walt
