I have installed two CentOS 4.3 boxes with LVS (from
http://mirror.centos.org/centos/4/csgfs/ ) but all boxes died withe this
error frequently:
kernel panic - not syncing: fs/block_dev.c:396: spin_lock
(fs/block_dev.c:c0361c0) already locked by fs/block_dev.c/287.
I have read from this thread http://threebit.net/mail-archive/centos/msg00243.html that this is an unsolved problem.
So i have installed the kernel-2.6.9-39.EL from testing repo, but the box diedi with another error:

So LVS is unusable because after of no more hourse of running the kernel go to panic.
There is a solutions to this problem?
I can help to test some patch or kernel.
Have somebody solved this situations?
Thanks
