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
