    USB flash, IOWAIT, and hanging

    Hello,

    Most of the time when using USB flash drives under Linux, the OS will lock up at 100% IOWAIT, with a load average of 12-18. Even my music stutters and stops.

    Using USB drives makes my Core I7 3.0GHz HyperThreaded act like a Pentium 2 running Vista. It's embarrassing. A client asks for a file, and it takes me 2 hours to copy it. This is a deal breaker. I've been trying to find a solution. If I can't, I'm sorry to say I'll be leaving Linux for something that can use USB drives. I've been using Ubuntu for 4 years, I'd hate to leave. Don't take that as threat, just a stark fact based on business decisions.

    Please help me solve this. I'll give you a Virtual Beer.

    I'll bump this. I experience the exact same thing. I swear I've tried every fix, kernel patch, etc under the sun. There's no reason this should be happening when on the same machine and a different OS it works just fine. It happens on every single laptop I've ever tried (1 Gateway, 1 Asus, 1 Toshiba, 1 Dell).

    Waiting 4+ years now for the magical solution...

    Right, I just discovered this is also a problem for me, https://bugzilla.kernel.org/show_bug.cgi?id=12309 is the closest that I have been able to get atm.
