freebsd stable - Apr 2005 - Using the 6-CURRENT twa driver on 5-STABLE.

Is it better to use the 6-CURRENT driver on 5-STABLE,  or the 3ware 9.2
Software Release for 5.x.

I see that there have been some changes between the two.  Are they
improvements,  applicable to 5-STABLE as well,  or just changes required
for 6-CURRENT?

It looks like the changes are probably optimisations,  but I'm not sure
whether that applies for 5-STABLE as well.

I've tried both,  and am currently using the 6-CURRENT driver on 2 of
our 4 5-STABLE boxes without any obvious ill effects.  Should I stop?

In either case,  would it be possible to commit one or the other quite
soon after 5.4-RELEASE?  (I'm assuming they can't go into 5.4-RELEASE).

Thanks,


Jason.

twa on 6 -CURRENT is essentially the same as the 9.2 release, except for
the changes needed to be able to build on 6 -CURRENT.  You should be able
to use it on 5 -STABLE without any problems.  I just want it sit in -CURRENT
for 2-3 weeks before I commit it to -STABLE.
