kernel 2.6.18 panic with multiple usb bulk using DM357

Stone lu — Fri, 03 Jul 2009 04:08:37 GMT

Hi,everyone. I'm using the SEED's DM357 Board and mv5 (kernel 2.6.18). I have some trouble when I use of two USB devices at the same time. I get a kernel panic with multiple usb bulk transfer (the panic message be shown in the bottom). These is a patch for this panic(http://marc.info/?l=linux-usb&m=122284678326862), but that kernel of version just not like me using now.How can I do to fix this kernel panic. Thanks!
