If you're able to reproduce while you're remoted in via ssh, then if you get the dmesg at least you won't have to spend time trying to save it somewhere since you'll have it on the remote system's terminal window.

https://www.kernel.org/doc/Documentation/sysrq.txt

So basically:
echo w > /proc/sysrq-trigger
dmesg
