when I start xawtv and alevt in the same window and press 'v' in xawtv,
bttv goes berserk, producing around 25 lines per second of debug stuffs.
(xawtv was also in fullscreen mode when I did this).
alevt quits just fine.

BTW. one quickie question about I2C:
when I switch channels in xawtv, I get at max 125ms latencies when running
rtc_latencytest. with the patch below around 1.5ms (same as without xawtv...).
so, I ask is this patch OK (safe, etc)?

Any change with latest updates from http://dl.bytesex.org/patches/ ?
I can reproduce with the latest bits. There was a state handling bug
when using both video + vbi recently through, not sure whenever the
fix made it into 2.6.10 or not.

I applied that All-2.6.10.diff.gz and now pressing 'v'
in xawtv caused nice freeze in a couple of seconds (sysrq+b did not work,
had to cycle power).
I didn't try alevt yet.

Yup... now with latest patch from dir 2.6.10-2 (All-2.6.10.diff.gz)
I had one funny experience. I was playing with 'v' in xawtv
(with alevt), and got Kernel panic - not syncing: Fatal exception
EIP is at check_slabp...
About 100 pixels from my windowmaker background got garbled (I also ran
xrefresh) while panicking ;-> and "rpm -V mozilla" showed three modified
libs.
I made screencap (digicam) of the panicked screen, ask for it if you care.
However, the libs were OK after reboot (maybe because no time for syncing),
but reiserfsck found vpf-10640 error for /var partition.
How to debug this kind of memory corruption?
I have gotten corrupted mozilla libs four times by using bttv...
here what got changed about two weeks ago in file
/usr/lib/mozilla/components/libgklayout.so

Thats typical for page cache corruption. The libs are read-only data
and thus never ever flushed back to disk, thus a reboot will fix it.
Creating some memory pressure to make the kernel drop the corrupted
pages from the cache should make it go away as well.
