Re: FreeBSD 6.2 on SPARC64/x86 with Promise IDE Controller

I think nullpt sent you off track when he told you to try
freebsd-performance.
I believe this is an issue for drivers and/or sparc (or
maybe current)

I think I have a TX2 too. I can try it on my Ultra 5 if more
testing
is required.

PS: I'm cc'ing Søren Schmidt, he's the maintainer of most of
the ata drivers

Maybe you're right that nullpt sent me off course.

However, thanks for pointing this e-mail to correct person
who needs to 
investigate the issue.
