Subject: [PATCH 2.6.19-rc2] scsi: megaraid_{mm,mbox}: 64-bit DMA capability fix
Date: Mon, 16 Oct 2006 12:08:43 +0400 [thread overview]
Message-ID: <45333E0B.7000905@sw.ru> (raw)
[-- Attachment #1: Type: text/plain, Size: 880 bytes --]
From: Andrey Mirkin (amirkin@sw.ru)
It is known that 2 LSI Logic MegaRAID SATA RAID Controllers (150-4 and 150-6)
don't support 64-bit DMA. Unfortunately currently this check is wrong and driver
sets 64-bit DMA mode for these devices.
