Hi,

Hi,

if I run "xawtv" [1] and then do a "grep -r toto /usr", my system quickly freeze. If there isn't any xawv running nothing happen. I don't try to use xawtv with grab mode (port 54) because I don't want to loose data by crashing again my / fs.

I retry it and I arrived to get some log (see the attach file).

But after rebooting, I had a big surprise, the / ext3 fs was corrupted and I need to run fsck by hand ....

Matthieu

I have done other tests.

If I use grabdisplay mode the problem doesn't occur.
If using overlay mode with port 54 the problem is present.

I have also try the cvs bttv driver and the problem isn't fixed.

Can someone look at it?
It seem that something is corrupting kernel memory because usb failed & ext3 failed...

I attached a new log when the problem appear.
Note that there are similitude with http://www.ussg.iu.edu/hypermail/linux/kernel/0412.3/0881.html and http://marc.theaimsgroup.com/?t=110531543900002&r=1&w=2
