Favored SAS controller

[mih at paranoia.ru]

Matthew,

I'm experiencing serious troubles on modern server hardware with LSI 
chipsets, 1030 for example.
FreeBSD-stable works stable just with scsi queue set in 1 (camcontrol 
tags .. -N 1, configuration - SMP, PAE)
Otherwise, it gets kernel panic sooner or later, depends on disk activity.
Could you please tell of mpt driver status ?
I see, -current gets active developement of the driver since last year.
Is it stable enough?
Do you plan to backport new mpt versions to -stable? When if so ?

Thank you, Mikhail.
