Can someone fix this? There's nothing to fix, because nothing is wrong; the warning message is purely informational. The reason for making it a warning was so that it would show up in the kerneloops project's records. The warning itself will be removed before 2.6.29 is released. Just out of curiousity, what sort of USB disk (vendor and product) are your 10d6:1101 and 0781:5151 devices? If you want to get rid of the warning in your own kernel, you can do it easily enough by removing the WARN() in last_sector_hacks() in drivers/usb/storage/transport.c. > Alan, this is for you :) In fact, Greg, it was _you_ who first suggested making this a WARN! :-) Never mind. I'll send in a patch to get rid of the warning in a week or two. Unless people start getting really upset and demand it sooner... Alan Stern ^ permalink raw reply [flat|nested] 6+ messages in thread
