It works fine for me. I do see occasional segfault-on-exec which I wonder whether is due to USB or VM/TLB magic; this smells somewhat like it could be both. I'll have to re-test things on an NFS root (and hope there's not MIPS/rspro-y issues with the NFS and NIC code. :) Is this USB alignment patch something that is needed for all MIPS/USB stuff, or just this specific SoC. If so, why? And will it potentially be an issue with other SoCs? Adrianhelp
