Unfortunately, no follow-up patch is forthcoming. I was able to use a spare DMA engine on our SOC to perform the memory zeroing, which eliminated the need for the enhanced memcopy() routine. Also, I am not familiar with the intricacies of MIPS exception handling for alignment issues, so I was not able to come up with a good solution for Shinya Kuribayashi's alignment trap issue questions. Please retract the patch. Jason McMullan MTS SW System Firmware NetApp 724.741.5011 Fax 724.741.5166 Direct 412.656.3519 Mobile [EMAIL PROTECTED] www.netapp.com
