I would also like to find a fix. Specifically: unplugging usb storage occasionally causes an oops. I'm guessing a race with use-after-free, but I haven't tracked it down. In my environment it has been hard to reproduce, and I wasn't able to grok anything useful in the trace. Are you seeing this behavior consistently? Perhaps the driver is freeing more than it should when a device is disconnected. -- Joshua Clayton Software Engineer UniWest 122 S. 4th Avenue Pasco, WA 99301 (509) 544-0720 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
