I am working in Device Driver group and it difficult to track request comin= g through emails. We can solve those request through emails which are minor= /medium in complexity. There are some group in LSI which has expertise to root cause issue and pro= vide better support than developers. Sometimes issue can be non-driver issu= e (e.a Can be hw issue/fw issues etc.) and those issue need customer inter= action and may be sometimes reproduction. So I request to contact LSI support channel ( at least for complex issues) = to get better tracking and speed up resolution. ` Kashyap From: Matt Thyer [mailto:matt.thyer@gmail.com] Sent: Wednesday, April 04, 2012 6:08 PM To: Desai, Kashyap Cc: Mike Tancsa; freebsd-stable@freebsd.org; McConnell, Stephen Subject: Re: 157k interrupts per second causing 60% CPU load on idle system On 4 April 2012 21:55, Desai, Kashyap > wrote: Mike, Have your purchase LSI controller through Channel or OEM ?

I purchased the Super Micro card off eBay through a seller with good reputa= tion. I've bought a couple of said cards through him now.
