Hi
Since upgrading to kernel 2.6.8.1, I _always_ get a kernel oops when
switching _from_ fullscreen to windowed mode in xawtv - I got the same
oopses with earlier kernels too, but very very rarely. See log below -
the call trace is always 100% identical, stack and registers are not.
Switching _to_ fullscreen works, but _only_ if the initial window size
is small (if it's 768x576 it oopses just the same). Happens if xawtv is
using overlay or grabdisplay, though in grabdisplay mode switching to
fullscreen doesn't work even if the initial window size is small.
I have disabled RANDR and the v4l XFree86 modules, and have these
options in the .xawtv file regarding the fullscreen options:
fullscreen = 768 x 576
use-wm-fullscreen = off
xawtv version is 3.91 (SuSE 9.1 package)
Tuner card is a miro pctv pro (bt848), i440 BX chipset.
I'm using these options in modprobe.conf:
options bttv vbibufs=8 combfilter=1 gbuffers=4 card=11 radio=0
debug_latency=1
bttv prints this information:
