Hi,
Hello.
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,
"2.6.37-gentoo-hardened" is based on what vanilla kernel (.36 or .37)?
It's based on .37.

[<ffffffff81166f7d>] ? prepare_logical_cluster+0x23d/0x760
A set of blocks reserved in prepare_logical_cluster() is exhausted
at znode_make_dirty() for some reasons. No ideas except inserting
debugging messages to figure out who is stealing the reservation.
Will try to reproduce on weekends..
Thanks,
Edward.
