I have not been getting crashes but the latest kernel has been losing network connectivity at random times. The only packages that may possibly not work with older kernels are packages related to the kernel like iptables or kernel modules. You should not have to worry about iptables as it has not been updated since release. I cannot say much else than that since I do not know what is on your box.
