The configuration I used to build 2.5.64-mm6 was the same as every other 2.5 build I've used recently. All of those included modular usb, so I don't believe it is that. In my case 2.5.64-mm6 is the only version on which I see this. My initial SWAG was some interaction between the new pcmcia core and usb, possibly at the pci layer. I only ever try very few mm kernel versions, so I don't have a whole lot of data at the moment. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
