The standard Alt-SysRQ- S,U,B
(That's sync-to-disk, remoUnt-ro (or just think of it as Unmount if you
like), reBoot.
It doesn't /always/ work, and Magic SysRQ is a kernel config option so
some folks might not have it enabled in their kernel (or the default
might be off), but when it's enabled and it /does/ work, it can save MANY
the HUGE headache!
For more details, /usr/src/linux/Documentation/sysrq.txt if your kernel
sources are in the standard location, or google it:

That's why I'm warning people.
I had my fill of data=writeback with reiserfs back before it got
data=ordered as the default, and know the evils of data=writeback from
first hand experience. That is, I'm sure, the biggest reason reiserfs
has the reputation for lack of reliability it does, because back before
data=ordered, it COULD and often DID eat people's files for breakfast!
