Hi Dave The subject for this should be "driver/net: enic: Try DMA 64 first, then failover to DMA 32"
The "32" got truncated, please add this while committing. Let me know if you want me to send another patch. thanks //govind On Wed, 4 Sep 2013, Govindarajulu Varadarajan wrote:
In servers with more than 1.1 TB of RAM, the existing 40/32 bit DMA could cause failure as the DMA-able address could go outside the range addressable using 40/32 bits. The following patch first tried 64 bit DMA if possible, failover to 32 bit.
