[SLUG] webcam woes Jaunty

2009-05-21 Thread Ken Foskey 

There is a problem with Jaunty and webcams that I have:

https://bugs.launchpad.net/ubuntu/+source/libv4l/+bug/359045


Webcams will occasionally work.

There is also a Kernel bug that crops up because of something with
cheese:

cheese: page allocation failure. order:5, mode:0x8004

Googling led me to this:

http://www.kernel.org/pub/linux/kernel/v2.6/testing/ChangeLog-2.6.30-rc4

Which I am not running:

Ubuntu SMP Fri May 1 19:31:32 UTC 2009 (Ubuntu 2.6.28-12.43-generic)


So all in all this is not very successful :-(

Wow.  Whatever that driver is, it asked for 2^5, or 32 physically
contiguous pages from the kernel.  /That/ isn't going to work well.

No, but that change is just to suppress the warning; apparently the
uvcvideo driver /should/ retry with a smaller request, so that
*probably* isn't an actual problem.
