Hi, I'm attaching a trace of kernel BUG that Firefox hits. It's 100% reproducible, every time I start the browser it hits the bug within several seconds, then whole system hangs. However I've never triggered the problem with any other application. I've tested 2.6.37-gentoo-hardened + reiser4 patch, and 2.6.36-zen kernels and both are affected. I'm happy to test patches or provide more info if needed. Thanks, Marcin
